For production machinery with constant torque (TL is constant, regardless of speed), a motor with hard characteristics should be selected, such as metal processing, lifting machinery, etc.

Rated current IN: The current when the rated power is output on the shaft under rated voltage (shunt excitation includes excitation and armature current).

​The control principle of the brushless DC motor, to make the motor rotate, the control part must first determine the position of the rotor of the motor sensed by the hall-sensor

The frequency of the rotating magnetic field of the stator is controlled and the rotational speed of the motor rotor is fed back to the control center for repeated correction, in order to achieve a...

The structure of the brushless DC motor stator is the same as that of an ordinary synchronous motor or an induction motor. Multiphase windings (three-phase, four-phase, five-phase, etc.) are embedd...

​Divided into two parts: stator and rotor. Note: Do not confuse the commutator pole with the commutator.

​The rotor part of the DC motor is composed of armature iron core, armature, commutator and other devices. Each component in the structure is described in detail below.
