The application and torque calculation of permanent magnet DC reduction motor

The permanent magnet DC reduction motor is a kind of DC reduction motor, which is obtained by using permanent magnet, mainly in some portable electronic equipment or apparatus, such as electric massager, electric bicycle, motorcycle, automobile, ship and mechanical equipment.

 

The permanent magnet DC reduction motor has simple structure, small volume, less material consumption and high efficiency.

 

Before calculating the electromagnetic torque of the permanent magnet DC reduction motor, first of all, it is known that:

The torque of the motor is proportional to the average current of the winding, which is TM = KtIav.

The inverse electric potential difference of the two-phase winding of the motor is proportional to the angular velocity of the motor, which is ELL=Keω.

Therefore, the average current in the motor winding is Iav=(Vm-ELL)/2Ra.

 

The calculation formula of the electromagnetic torque of permanent magnet DC reduction motor is:

Tm=δ·(VDC·Kt/2Ra)-Kt·(Keω/2Ra)

Among them, Kt and Kt are the structural constants of the motor, and ω is the angular velocity of the motor. So, by this formula, we can know that if ω is certain, then the electromagnetic torque of the motor can be changed by changing δ.
