Abstract

The invention discloses a disc type motor with an adjustable air gap, belongs to the technical field of motor equipment, and is designed for solving problems that the air gaps of existing disc type motors are not adjustable and are not convenient to use. The disc type motor with the adjustable air gap comprises a motor shell, a stator which is arranged in the motor shell, a stator winding which sleeves outside the stator, a rotor which is arranged to be coaxial with the stator, a bearing which is connected with the rotor, a bearing cap which is arranged at the external part of the motor shell and connected with the bearing, and a driving device which is used for driving the bearing cap to rotate. The bearing cap can rotate relative to the motor shell. The bearing cap can adjust the gap between the stator and the rotor via the bearing. The disc type motor with the adjustable air gap is convenient to use, high in reliability, low in manufacturing cost and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to a 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. Usually, the stator is a coil, and the rotor is a permanent magnet or a disc with permanent magnets. Due to its light weight and structure It is widely used because of its thinness and other characteristics. [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 the motor. [0004] The air gap value of the exist...
