Positive inversion of Customized high speed dc motor
The DC motor has a fast response speed and a large starting torque. The characteristics and advantages of the DC motor are that the performance of the rated torque can be provided from zero speed to rated speed. We know that the DC motor in many situations not only requires the motor to have good starting and adjusting characteristics, but also requires the motor to have positive reverse characteristics.
So how to realize DC motor positive reverse?
The positive and negative inversion of DC motor is usually achieved by changing the logic relationship of inverter switch and changing the turn order of each phase of armature winding.
In order to make the motor produce the maximum average electromagnetic torque to ensure the symmetrical operation of the motor, it is necessary to design the position relationship between the rotor position sensor and the rotor main magnetic pole and the stator winding group, as well as the correct logical relationship.
Positive / reverse control
The direction of operation of DC motor can be controlled by controlling terminal and terminal switches. The terminal can be used with passive contact switches or with other control units with open circuit collector circuits.
When not connected to the terminal, the motor will run clockwise(facing the motor shaft) and vice versa. In order to avoid damage to the DC drive, the motor should stop moving before running to replace the steering when replacing the motor steering. Avoid direction control during motor operation. The DC drive provides the user with a pulse signal proportional to the speed of the motor through the terminal speed.
