Abstract

The invention provides a single-phase cylindrical linear vibration motor, which comprises a motor stator, a motor rotor and a bearing, wherein the motor stator comprises three U-shaped stator cores, two non-magnetic circular rings and three concentric winding coils; the motor rotor comprises a rotor sleeve, four rotor teeth and five permanent magnet rings; the motor stator part and the motor rotor part are in clearance fit, namely the three concentric winding coils are horizontally arranged; U ends point to the bearing; and the concentric winding coils and the rotor teeth are oppositely arranged. According to the single-phase cylindrical linear vibration motor provided by the invention, a rotor yoke part is omitted; the motor manufacturing process is simplified; the slot utilization rate is improved; the propulsive force of the rotor is increased; the sealing property is good; the structure is simple and firm; the end effect and the normal magnetic pull force of the motor are removed; the motor reliability is high; the requirements of sports occasions of reciprocating linear vibration can be met; and the single-phase cylindrical linear vibration motor is suitable for popularization and application in industrial linear vibration.

Description

technical field [0001] The invention relates to a linear motor, especially a single-phase cylindrical linear vibration motor with large propulsion force per unit volume. 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 ...
