Using a rotation tester when installing a motor saves time and prevents problems such as driving the load backward. In some cases, you must get the motor rotation correct or massive damage will occur.

Startup techniques employed to overcome the problem of determining magnet position in BLDC designs. Cost-saving and power-efficiency incentives using sensorless motor drivers. Motor-driver solutions ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.
