Single-phase capacitor motors use only one capacitor, which is called the "working capacitor." Whether it is starting or operating normally, it always starts both ends of the winding and running winding coils....

The shaft breakage of the motor occurs at the root of the shaft extension and the bearing of the shaft extension....

This method is similar to the stepper motor control method. The motion controller sends a "pulse/direction" or "CW/CCW" type pulse command signal to the servo drive; the servo drive works in the position control mode, and the position closed loop is completed by the servo drive ....

Motors can be roughly divided into DC motors, AC motors, auto-angle motors, stepper motors, resolvers, shaft encoders, AC/DC motors, tachogenerators, induction synchronizers, linear motors, piezoelectric motors, motors 13 major categories such as generating units and other special motors....

The same winding of the motor is made up of many turns (turns) of wire. If the insulation is not good, the coils stacked together will be short-circuited. In this way, it is equivalent to that some coils are directly short-circuited and do not work....

For the efficiency test of motors, the measurement methods adopted by different motors are different....

Chassis dynamometer is a special metering device used to measure the output power, torque (or driving force) and vehicle speed (or driving wheel speed) of the driving wheels of automobiles....

The structure of the dynamometer is very simple. It consists of a cabinet and a test bench. The test bench is often called the dynamometer head. It generally refers to a model in which a torque speed sensor and a brake are integrated....
