Problems solved by technology

Due to the ferromagnetism of the iron core, the permanent magnet rotor can only provide a magnetic field to the rotor winding from one direction, and the unit magnetic flux density is low. In order to ensure the transmission efficiency, the volume of the governor has to be large enough to carry enough The permanent magnet rotor and winding

Abstract

The invention discloses a permanent magnet speed regulator comprising a driving shaft, a driven shaft, permanent magnet rotor sets, rotor windings, a speed regulating device and a high molecular plastic carrier. The permanent magnet rotor sets are connected with the driving shaft in a transmission way. The high molecular plastic carrier is connected with the driven shaft in a transmission way. The axes of the driving shaft and the driven shaft are overlapped. The permanent magnet rotor sets are provided with permanent magnet rotors and used for generating a varying magnetic field in rotation of the driving shaft. The rotor windings are arranged on the high molecular plastic carrier. The rotor windings are connected with the speed regulating device and used for regulating the rotating speed of the driven shaft. The high molecular plastic carrier is manufactured by high molecular plastics so that the supporting structure can be optimized, the rotational inertia can be reduced, the servo-actuating performance of the rotor windings can be enhanced and regulation is enabled to be more rapid and accurate; and the wear rate between the rotor windings and the carbon brush can be reduced so that the service life can be enhanced.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a permanent magnet governor. Background technique [0002] Permanent magnet speed control technology is a breakthrough new technology developed internationally in recent years, and it is an applicable technology for speed control and energy saving of centrifugal loads such as fans and pumps. It has the characteristics of high efficiency and energy saving, high reliability, no rigid connection to transmit torque, can be applied in harsh environments, greatly reduces the overall system vibration, reduces system maintenance and prolongs the service life of the system, making it an energy-saving technology for fans and pumps. Top choice for remodeling. [0003] The problem is that the rotor windings of the existing permanent magnet governors are all attached to the supporting structure of the iron core, whether they are of the drum type or the disk type. Due to the ferromagne...
