Stepping motor overcurrent detection and protection device

摘要

An overcurrent detection and protection device for stepping motors has means for detecting an overcurrent condition in the power supply to a stepping motor. Means responsive to the detecting means rapidly provides a signal to the stepping motor drive system causing the current to terminate and to remain terminated for a predetermined interval of time, at the end of which interval the device resets itself causing the current to resume. The device is sufficiently fast-acting to protect electronic components such as transistors.
