Abstract

The invention discloses a single-phase cylindrical linear oscillation motor, and the motor rotor is provided with a permanent magnet ring, thereby improving the effective magnetic flux of the motor. The rotor sleeve is made of a non-magnetic medium, so that the material consumption of the motor iron core is effectively reduced; by adopting the stator iron core with the annular groove inside, the concentric winding coil can be fully embedded in the stator groove, the motor manufacturing process is simplified, and the groove utilization rate is improved; and the stator grooves are separated by the non-magnetic rings, so that the magnetic circuit of the stator core is divided, a short magnetic circuit is formed, and the propulsive force of the motor is increased.

Description

technical field [0001] The invention belongs to the technical field of linear motors, in particular to a single-phase cylindrical linear oscillating motor. Background technique [0002] Linear motor is a transmission device that can directly and quickly convert electrical energy and mechanical energy generated by linear motion. Since the linear motor does not need an additional device to change the rotary motion into a linear motion, the structure of the system itself is greatly simplified, and the quality and volume are reduced. In the field of linear drive, linear motors can be directly driven, which can eliminate various positioning errors caused by intermediate links. There are various structures of linear motors. As a motor with a special structure, cylindrical linear motors are the structural evolution of ordinary rotating motors. Cutting and straightening the rotating motors along the radial direction can obtain flat linear motors. The motor, and then the flat motor...
