Title: Stator for molded motor and manufacture thereof
Inventor: YASHIRO OSAO
IPC: H02K5/08
Filed: 1994-02-18
Abstract: PURPOSE:To enhance adhesion between a core and a synthetic resin when the stator of a molded motor is manufactured while covering the stator with a synthetic resin up to the outer periphery of the stator core. CONSTITUTION:Notches 22 are made in the outer periphery of thin plate core pieces 21a, 21b,...,21n at an interval of angle alpha 1. The core pieces are then laminated up to a prescribed thickness while rotating by an angle beta1 different from alpha 1 thus distributing the notches 22 all over the outer periphery of the stator core 21. A synthetic resin injected into the notches 22 is cured to enhance adhesion between the stator core 21 and the synthetic resin thus producing a molded motor having stabilized quality in which the synthetic resin is not stripped off easily from the stator core.

Filed: 1982-02-15
Abstract: PURPOSE:To start an emergency control circuit even in case of a fault occurring to a reset signal generation part by executing plural instructions for generating characteristic reset signals in prescribed order and monitoring the generation order of the reset signals. CONSTITUTION:A start signal outputted from a counting part 5 at prescribed cycles is transmitted to a counting part 8 and an order part 9. The counting part 8 controls the order part 9 every time when the start signal is received to transfer the received start signal to the 1st and the 2nd instruction execution parts 10 and 11 alternately. The execution parts 10 and 11 while in normal operation transfer the 1st and the 2nd reset signals to an order monitoring part 12 alternately at prescribed cycles. The monitoring part 12 transfers the 1st and 2nd reset signals transferred irregularly by turns to a fault detecting timer 7, which is reset on the reception of every signal, so that the emergency control circuit 2 is never started. When >=2 successive signals are inputted, the monitoring part 12 transfers neither of them to the timer 7, so the timer 7 is never reset and starts the circuit 2 a specific time later.

Title: Pulse width modulation control inverter unit
Inventor: KAMIMURA TAKESHI
IPC: H02P27/06
Filed: 1991-02-18
Abstract: PURPOSE:To maintain a high modulation factor by lowering DC input voltage to a PWM inverter or an AC input, voltage to a rectifier, in step or continuously, as the rotational speed lowers. CONSTITUTION:When an induction motor 5 is operating in high speed region, a PWM inverter 4 receives DC power through an AC power supply 1 and a main rectifier 2. When the induction motor 5 enters into low speed region, a switch 13 functions to rectify AC power on the secondary of a transformer 11 through a rectifier 12 and feed thus rectified power to the PWM inverter 4. In other words, when the output of the PWM inverter 4 is lowered in order to operate the induction motor 5 at a low speed, DC input voltage to the PWM inverter 4 is also lowered and thereby the content of higher harmonics is prevented from increasing due to lowering of modulation factor.
