Abstract

The utility model relates to a double-controlled AC stepless speed-regulating motor, which belongs to the technical field of the stepless speed-regulating motors, and comprises the motor, an outer casing, and an armature. The utility model is characterized in that the shaft of the motor is fixing connected with a magnetic pole; the armature which is fixedly connected with the output shaft of the motor is arranged outside the magnetic pole; a magnetic conductor is arranged at the corresponding position of the armature in the outer casing; a field winding is arranged in the magnetic conductor. The utility model has the advantages of large force moment, small starting current, long time rotation blocking without burning the motor, simple structure, convenient operation, less power loss, long service life, etc.

Description

Two control AC stepless speed changeable motor

The utility model relates to motor with stepless speed regulation, particularly a kind of two control AC stepless speed changeable motor.

The utility model patent application a few days ago, the open AC stepless speed changeable motor of using that reaches on the market, as Chinese patent application 881067504 disclosed " double-rotor machine ", mainly comprise: moving stator, rotor, coil, several parts of base, this machine adopts the output shaft power output, use need be passed through decelerator transmission or planetary gear transmission, floor space is big, power loss is serious: need in the motor operation course in stator, two ends of rotor brake gear to be set respectively, moving stator of control and rotor rotation, cause complex structure, defective such as operation sequence is many.

Goal of the invention of the present utility model is to overcome above-mentioned defective and provides a kind of moment big, and starting current is little, and long-time stall does not burn motor, and simple in structure, easy to operate, power loss is little, two control AC stepless speed changeable motor of long service life.

Foregoing invention purpose of the present utility model realizes by following technical proposals:

A kind of two control AC stepless speed changeable motor, comprise: shell, motor shaft, several parts of base are formed, it is characterized in that base passes through the Bearing Installation motor shaft, motor shaft is settled shell by bearing, the interior motor shaft of shell [5] is provided with internal rotor iron core and coil, the outer motor shaft of shell is provided with slip ring, carbon brush, and the slip ring lead-in wire connects with coil; Internal rotor corresponding position shell internal fixation is provided with outer rotor iron core and coil, and the outer motor shaft of shell is provided with slip ring, carbon brush, and the slip ring lead-in wire links to each other with winding wire.

Motor shaft is provided with internal rotor iron core and coil in the described shell, and the outer motor shaft of shell is provided with slip ring, carbon brush, and purpose is that power supply imposes on the internal rotor coil current by carbon brush and slip ring and constitutes a rotating magnetic field with rotor core.

The shell internal fixation outer rotor iron core and the coil of described internal rotor correspondence position, the outer motor shaft of shell is provided with slip ring, carbon brush, and the slip ring lead-in wire links to each other with winding wire, purpose is to form the rotating magnetic field of a pair of control by carbon brush slip-ring with internal rotor, realizes the control of relative motion between the birotor.

In order to keep permanent torque, motor arbor output is provided with by magnet, and the tachogenerator that coil and control device are formed is realized the differential adjustment of whole motor.

Two control AC stepless speed changeable motor of the utility model structure, it is big to have moment, and starting current is little, and long-time stall does not burn motor, and simple in structure, easy to operate, power loss is little, advantages such as long service life.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model:
