Problems solved by technology

If the air gap is too large, the power factor of the motor will decrease. If the air gap is too small, the ventilation performance of the motor will decrease, which will affect the heat dissipation of the motor and increase the temperature rise of the motor.
[0004] The existing control methods are all based on the ordinary disc motor, the gap of which is usually fixed, and th...

Abstract

The invention discloses an air-gap-adjustable disc-type motor and a control method thereof, belongs the field of a motor device and a control method thereof, and is to solve the problem that it is inconvenient to adjust an air gap of an existing disc-type motor and the like. The air-gap-adjustable disc-type motor comprises a housing, a stator arranged in the housing, a stator winding sleeved outside the stator, a rotor arranged coaxially with the stator, a bearing connected with the rotor, a bearing cap arranged outside the housing and connected with the bearing, a turbine motor for driving the bearing cap to rotate, a permanent magnet arranged between the stator and the rotor, and an end cover, wherein the end cover and the housing form a cavity. The invention also provides the control method of the air-gap-adjustable disc-type motor. The air-gap-adjustable disc-type motor is convenient to use, high in reliability and low in manufacturing cost. The control method of the air-gap-adjustable disc-type motor is high in control precision and good in control effect.

Description

technical field [0001] The invention relates to a disc motor with adjustable air gap and a control method based on the disc motor with adjustable air gap. Background technique [0002] The disc motor includes a stator and a rotor, the stator is mounted on a flat base plate, and the rotor is covered on the stator. Typically, the stator is a coil and the rotor is a permanent magnet or a disc with permanent magnets glued on it. Disk motors are widely used due to their light weight and thin structure. [0003] The air gap refers to the air gap between the stator and the rotor of the motor. The size of the air gap will affect the starting torque of the motor and the efficiency of cutting the magnetic induction line during operation. If the air gap is too large, the power factor of the motor will decrease. If the air gap is too small, the ventilation performance of the motor will decrease, which will affect the heat dissipation of the motor and increase the temperature rise of t...
