VORRICHTUNG ZUM REGELN DER GESCHWINDIGKEIT VON PULSBREITENMODULIERTEN ELEKTROMOTOREN, INSBESONDERE VON GLEICHSTROMMOTOREN.

摘要

Signals from an encoder (3) on the shaft (2) of the motor (1) are fed back into a control circuit (4) where a microprocessor (5) and a peripheral control unit (10) cooperate with an amplifier (8) to regulate the speed of the motor. To reduce the cost of hardware components the microprocessor is linked by a data and address bus (9) to the peripheral control unit and, by the same bus to a memory (11) which can be programmed to regulate the off-time of the pulse duty cycle via binary registers, counters and comparators.
