Permanent magnet square wave motor direct-driving intelligent speed regulation stirring reactor transmission device

Abstract

The invention discloses a permanent magnet square wave motor direct-driving intelligent speed regulation stirring reactor transmission device and relates to a transmission device. The transmission device comprises a six-phase permanent magnet square wave motor, a controller, a coupling and a connecting flange, wherein the permanent magnet square wave motor comprises a motor shaft, a rotor component, a stator component, a rear end cover, a front end cover, a position sensor and a shell; stator windings of the permanent magnet square wave motor are three-phase or multiphase windings, e.g., six-phase windings, and the two groups of three-phase windings U, V, W and R, S, T are independent, and the corresponding windings are in the spatial difference of 30<degree>E; and the six-phase windings of the permanent magnet square wave motor are connected in a star shape, and rotor steel magnets are bonded in a surface-mounted mode. According to the permanent magnet square wave motor direct-drivingintelligent speed regulation stirring reactor transmission device, a reducer on a traditional stirring device is omitted, and the technological requirements for low speed and large torque of a stirring reactor are met; and especially in the pharmaceutical and food industries, the phenomenon of oil leakage can be thoroughly eradicated, so that repair and maintenance are reduced, and efficiency isimproved.

Description

technical field [0001] The invention relates to a transmission device for a stirred tank, in particular to a permanent magnet motor with a pure square wave current waveform, which directly drives an intelligent speed-adjustable transmission device for the stirred tank. Background technique [0002] The traditional stirring tank transmission system uses asynchronous motors and reducers to transmit power to gears, pulleys or central connecting rods to drive the equipment to rotate. Since most of the stirring process operates at low speed and high torque, the power composed of motors and reducers is generally used. The obvious disadvantage of the transmission mode of this system is: the motor and the reducer are connected together, which increases the height of the stirring tank; the reducer is prone to oil leakage and oil leakage, especially in the pharmaceutical industry and food industry. Pollution can cause A variety of serious diseases occur, and there are potential safety...
