The composition of K mechanism with permanent magnet DC motor

The K mechanism with permanent magnet DC motor is composed of a motor main body and a driver, and is a typical electromechanical integration product. Its stator windings are mostly made into a three-phase symmetrical star connection method, which is very similar to a three-phase asynchronous motor; a magnetized permanent magnet is adhered to the rotor, and a permanent magnet DC motor is used for the K mechanism in order to detect the polarity of the motor rotor. A position sensor is built in.

 

The drive for K mechanism with permanent magnet DC motor is composed of power electronic device and integrated circuit. Its function is to accept the start, stop and brake signals of the motor to control the start, stop and brake of the motor; accept the position sensor signal and positive and negative The turn signal is used to control the on/off of each power tube of the inverter bridge to generate continuous torque; to receive speed command and speed feedback signal for controlling and adjusting the speed; to provide protection and display, etc., the main circuit is a typical voltage The intersection-direct-crossing circuit, the inverter provides a symmetric alternating rectangular wave of equal amplitude 5-26KHZ modulated wave.

 

The K mechanism uses the position sensor code of the permanent magnet DC motor to make the position of the combined two-phase winding of the energized magnetic field ahead of the rotor magnetic field axis position, so no matter where the starting position of the rotor is, the motor will generate a sufficient start at the moment of starting. Torque, so no additional start winding is required on the rotor. Since the motor is operated in a self-controlled manner, it does not add a start winding to the rotor like the synchronous motor with heavy-duty starting under variable frequency speed regulation, nor does it generate oscillation and out-of-step when the load is abrupt.
