Abstract

The invention relates to a high-efficiency short-stroke linear reciprocating oscillation motor, belonging to the technical field of motors. The invention solves the problem that the traditional short-stroke linear reciprocating oscillation motor using a support leaf spring as a motor rotor support and elasticity restoring force generator has low system efficiency. The high-efficiency short-stroke linear reciprocating oscillation motor comprises a motor shell, two end covers, a motor stator, a motor rotor, two magnetic power accumulators and two linear magnetic bearings. Two power accumulator stators are respectively located on the axial inner side surface at the through-hole end in the centre of two end covers; two power accumulator rotors are respectively fixed on two axial end surfaces of the motor rotor; both the power accumulator stator and the power accumulator rotor are annular rare earth permanent magnets or axial symmetry type rare earth permanent magnets; both the bearing stator and the bearing rotor are cylindrical rare earth permanent magnets; two bearing stators are respectively sleeved and fixed on the inner surfaces of the central through holes of two end covers; two bearing rotors are respectively sleeved at both ends of an output shaft of the motor rotor; and the bearing stator is arranged opposite to the bearing rotor. The invention is suitable for a linear reciprocating oscillation motor.

Description

technical field [0001] The invention relates to a high-efficiency short-stroke linear reciprocating oscillating motor, which belongs to the technical field of motors. Background technique [0002] A common structure of a short-stroke linear reciprocating oscillating motor is as follows: image 3 shown. It is mainly composed of motor stator, motor mover and supporting leaf spring. The specific structure of supporting leaf spring is as follows: Figure 4 As shown, it is fixed on both sides of the motor stator in the axial direction and connected to the output shaft of the mover. On the one hand, the supporting leaf spring keeps the motor mover in the inner cavity of the motor stator to prevent the motor mover from radially contacting the motor. The inner cavity of the stator is in contact. On the other hand, the supporting leaf spring will also generate an axial restoring force, so that the spring-mass system composed of the motor mover and the supporting leaf spring will res...
