Automotive Testing System
Supporting the development of next-generation automobiles by
shortening development time through high precision and high relia
We developed low-inertia motors equivalent to a car engine that reduced the required motor inertia to
one-tenth the previous value. These engine simulators were made possible through a variety of weightsaving technologies. We have also enabled the dynamic testing of automotive parts by combining highspeed torque control, including dead-beat control (electric current control method for implementing ahigh-speed torque response) with mechanical systems equipped with moving mechanisms to which
various test pieces can be easily attached.

Maintenance
Maintenance and consumable parts to keep equipment running optimally
It is extremely important to conduct diagnostics and maintenance ona regular basis to keep your electric equipment running optimally at all
times. And having this job done by technicians well versed in advanced
function/advanced performance products and who use their experienced
eyes to spot problems keeps it all running in peak condition.
Legally mandated maintenance on emergency generators and otherequipment that complies with the Fire Service Act is carried out by avariety of licensed technicians. There are different kinds of maintenance,
including spot maintenance and routine maintenance, but we recommend
an annual maintenance contract so that you know how your equipment isholding up over time and can keep operational costs under control. Let us
assist you in purchasing the consumable parts and maintenance parts tokeep your industrial equipment operating optimally.

Products subject to maintenance● All industrial electric equipment (including DC control equipment)● Electrical components for generators, engines, and auxiliary
equipment● Electrical components for water supply equipment, pumps, andauxiliary equipment

Repair & Overhaul
Preventative maintenance for preventing problems before they occur
The reliability of electrical equipment parts drops as they
degrade and wear out over time. But accidents caused bydegraded or worn parts are not limited to the parts themselves.
They can also spread to healthy parts as well. Preventative
maintenance is essential for preventing problems before theyoccur and keeping equipment running in a stable manner
because it allows you to systematically repair and overhaul
equipment based on operation time and visible signs gleaned
from inspection results.

Products subject to maintenanceRotary machine equipment:
DC motors and DC generators●

AC motors and AC generators

Repair of control equipment and industrial control
equipment● Overhauls of generator electrical parts and engines● Overhaul of water supply equipment parts and pumps●

Example of motor disassembly/repair
Preventive maintenance is performed by disassembling motors, cleaning and drying rotors, stators, and other parts, andthen impregnating insulation material and replacing bearings and other components.

Pre-maintenance33

Post-maintenanceReform & Renewal
Renovations for improving productivity and safety updates for life cycles
In response to social demands, equipment at various
facilities is constantly being renovated and updated to meetneeds such as improving productivity, upgrading systems,
securing operational safety, reducing production costs bylowering energy expenses, and reducing CO2 emissions toachieve environmentally friendly operations. We take thecustomer’s perspective on these needs and meet them bycombining our latest technologies with our field know-how.
We then propose the most rational renovations and updates
based on the unique lifecycle of each customer’s equipment
and facilities.

Examples of renovations and updates● Conversion from DC to AC motors (inverter drive)● Conversion of AC commutator motors to inverter drives● Updating of electrical parts that are no longer made● Updating of worn controllers, including PLC● Conversion of fixed-speed drive equipment to variable
speed● Conversion of mechanical transmission to electrictransmission● Updating of electrical equipment that has reached its
maximum service life

Example of water supply equipment update
Updating the control panel and the motor to the latest inverter drive creates a system that saves energy andhas low pressure variability
