In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

It is often necessary for persons other than licensed electricians to perform minimal electrical work in a commercial or industrial facility. This work must be performed in the same safe manner as all ...

In today's rapidly evolving electric vehicle technology landscape, Wuhan Lidian Automotive Electric Control System Co., Ltd. (stock code: 688667) has once again captured industry attention. According ...

Using a multi-shunt-based current-monitoring circuit with a 50-MHz op amp delivers an overcurrent detection response time of ...

CRRC Times Electric has made significant breakthroughs, with a new oil-cooled motor patent that addresses the power consumption of oil pumps in low-temperature environments.

Multiple motors and independent control of each wheel of an EV provides optimal performance and handling. But the complexities of implementation should be understood so that results can match ...
