General Precautions！

Notice●When you connect a power cable to the motor, always refer to the connection diagram
provided in the motor s terminal box or follow the instructions mentioned in its speciﬁcation
sheet or this document. If the motor is not equipped with a terminal box, insulate the cableconnections adequately.
●Don t bend, pull or press the power cable and the motor s lead wires to avoid an electric
shock.
●Ground the motor by using its earthing terminal to avoid an electric shock.
●Before starting the connecting work, always isolate the motor from its power supply to avoid
an electric shock.
●To prevent the motor burning and a ﬁre, check to see that the supply voltage of your powersource conforms to the rated one mentioned on the motor s nameplate.
●When you ﬁnish the connecting work, don t forget to close the motor s terminal box with its
cover to avoid an electric shock.
●Use a power cable whose capacity conforms to that of the power source. Deﬁciency in cablecapacity will result in the meltdown of the cable s insulation sheathing, causing insulation
failure and an electric shock or a ﬁre.
●When you measure the motor s insulation resistance, don t touch the terminal to avoid anelectric shock.
●Conduct the cabling, connecting and wiring works in accordance with the local standards ofthe electrical equipment work and the wiring work as well as the regulations of the powercompany.
●Protective devices are not provided for the motor as standard accessories. Installation of an
overload protective device is obliged in Japan and may be obliged by the electrical equipment
work standard of your country. Aoki Seimitsu Kogyo recommends the installation of otherprotective devices, such as earth leakage breaker, to prevent an electric shock, ﬁre, injury
and/or damage.
●For star-delta starting, provide its starter with an electromagnetic switch (three-contacttype) on the motor s primary side to prevent a ﬁre.
●Don t use a starting capacitor to operate the motor. It will rupture in the middle of operation.
●Take care not to damage the vinyl sheathing of the starting capacitor to avoid an electric
shock.
●Voltage drop over the cabling distance should be less than 2%. A long cabling distanceallows a large voltage drop, which may result in failure to start up the motor.
●When you want to rotate the motor in the reverse direction, stop it once and start to turn it in
the reverse direction not to damage the motor by reciprocal operation with a plugging relay.
●For the motor with a brake system, don t supply power to the brake coil when the motor
stops to avoid the coil burning and a ﬁre.

●Wiring to the motor●Daily inspection

Connect the motor s lead wires as shown in the ﬁgures below.

Conduct a daily inspection on the matters listed below.
●Check to see that neither oil nor grease leaks from the product.
●Check to see that the product s surface temperature is neither excessively high nor increased
sharply. On the top surface of a gearbox, measurement with a thermometer should not exceed 40
degree Celsius above the ambient temperature.
●Check to see that the product does not generate abnormal noise and vibration and that its
performance does not change suddenly.
●Check to see that the product does not smell burnt.
●Check to see that the product rotates at its designated revolution.
●Check to see that the play of the output shaft is adequate.
●Check to see that the locking bolts do not get loose.
●Check to see that the chains and V-belts are not loosened excessively.
●Check to see that the supply current does not exceed the rated one mentioned on the product s

●Wiring to the brake
For the motor with a brake system, wiring to the brake has been ﬁnished in our factory before shipment.
You can use the motor as it is.
●Change its terminal connections for those applications listed below.
a. AC breaking: When you want to shorten the down time or to install a phase-advancing capacitor.
b. AC operating: When you want to install an inverter or to operate the brake separately. (With aninverter installed in the motor, brake operation during a high-speed rotation at 60Hz or above will
accelerate the abrasion of the brake lining.)
c. DC breaking: When you want to use the motor for an elevating system (with negative loads) or tosecure the stop accuracy.
●When you want to drive the motor with a brake system by means of inverter or start it up at a lower
voltage, always supply electric power to the brake from the primary side of the inverter or the
low-voltage starter. Operate it also with DC or AC switching.
●Always use the power unit provided for the motor with a brake system or the one designated by Aoki
Seimitsu Kogyo. Use of an unauthorized power unit will nullify our accountability for the performanceof the brake.

5.Operation！

！

Notice●Don t operate the motor with its terminal box cover left open to avoid an electric shock. Afterthe electrical work, don t forget to reinstate the cover.
●Whenever you notice something abnormal, stop operation immediately to avoid an electric
shock, injury and/or ﬁre.
●Don t operate the motor at a load exceeding its rated capacity to avoid injury and/or damage.
●Don t loosen the lubrication plug during operation. Heated lubricant may spout out, resulting
in a burn.
●Don t touch the energized parts of the single-phase motor s starting capacitor until complete
discharge of electricity to avoid an electric shock.

●For the motor with a lubrication port, follow the instructions printed on a label and purge air before
opening the lubrication plug to release its internal pressure.
●For the motor with an oil gauge, check to see that oil level stays at the center of the gauge.
●For the oil-lubricating motor, start it with no load and gradually increase the load for running-in. Checkto see that the motor does not generate abnormal vibration, noise or physical shock.
●When you start up an oil-lubricating motor after the shutdown for a long period of time, operate it at alight load until it is thoroughly lubricated.
●Check to see that the brake exciting voltage conforms to the motor s rated one at the brake s leadwires.

●Precautions on operation！

Danger！

Notice●Replacement of grease
For the grease-lubricating product, grease is sealed in it in our factory before its shipment. You may
use it as it is.
Although you do no need to replace the grease, overhaul of the product after the operation of 20,000
hours will contribute to the prolongation of its service life.

●Replacement of an oil seal
Oil seal naturally has its own service life. After being used for a long period of time, it will lose its
sealing eﬀect. Replace oil seals every one or two years in normal operating conditions. Replace themevery year when they are exposed to high temperatures, used in harsh environment such as continuous
operation or installed in clean working environment.

●Maintenance of a brake system●Preparation
Danger●Replacement of lubricant
For the oil-lubricating product with a lubrication port, replace its lubricant in the following manner.
●The product is ﬁlled with Bon-Knock M of JX Nippon Oil & Energy Co., Ltd. (New Japan Petroleum) asa standard lubricant in our factory before its shipment. Although you may use it as it is, replacementof the lubricant after the product s running-in at a light load will contribute to the prolongation of its
service life.
●Replace Bon-Knock M lubricant after the initial operation for 500 hours and every 2,000 hours
thereafter. You should replace it at shorter intervals when the lubricant deteriorates excessively.
●When you replace the lubricant, discharge the used one while it is still warm after operation. Flush theinside of the product with a ﬂushing oil and charge it with a fresh lubricant up to the oil gauge s
marked level.
●Use the designated lubricant or its equivalent as far as possible. Don t mix the lubricants of diﬀerent
brands. Mixture of diﬀerent lubricants may aﬀect the product s performance and cause oil leakage.
●The viscosity of standard lubricating oil varies according to model numbers. Please refer to thetechnical data written in the catalogue.

●During operation, don t touch or approach to the motor s rotating parts, such as shaft, toavoid being caught and getting injured.
●If a power failure occurs during operation, always turn oﬀ the motor s power switch to avoid
injury and/or damage when the power supply is recovered.
●During operation or even not in service, the motor is fairly heated up with power supply. Don t
touch it to avoid a burn.
●When you want to rotate the motor in the reverse direction, stop it once and start to turn it in
the reverse direction. Without stoppage, the motor may not change its rotating direction but
run away.

Brake systems deﬁnitely need regular maintenance. Conduct inspection and maintenance on thematters listed below.
●Check to see that the brake s set screws are intact and tightened adequately.
●Check to see that neither water nor oil penetrates into the brake system.
●Remove abraded particles from the brake disks periodically with compressed air or by vacuum cleaner.

●Adjustment of brake gaps
●Electromagnetic brake works with frictional force. After being used for a long period of time, its
frictional face wore out, widening the gap between the brake disks. When the gap exceeds a certain
distance, excitation of the brake does no longer activate its armatures. This distance is called acritical gap. Table 1 shows the optimum and critical gaps of the brake disks, depending on the motor
capacities. When the distance approaches a critical gap or as required, adjust the brake gap in theprocedure discussed below.
SB Brake Gap Adjustment Procedurea. Turn the manual release lever (1 in Figure 2) and remove it beforehand. Remove the brake covers (2and 3) and expose the brake body.
b. Adjust the distance between the brake disks at an optimum gap by loosening the lock bolt (4) andturning the 3 adjusting bolts (5). After the adjustment, tighten the lock bolt (4) ﬁrmly.
c. Check the gap at 3 points along the circumference, which are separate from each other at 120
degrees, to make it sure that the optimum gap is set at all the measuring points. Reinstate thebrake covers (2 and 3) and the manual release lever (1).
