Description

A kind of energy-conservation water-cooling permanent magnet frequency control three phase electric machine
Technical field
The utility model relates to a kind of motor, particularly a kind of energy-conservation water-cooling permanent magnet frequency control three phase electric machine.
Background technology
Mainly there are following 2 problems in the radiating mode of motor commonly used at present: motor adopts traditional air cooling way on one, and equipment adopts non-enclosed structure, causes the operation noise of equipment itself bigger; The 2nd, the heating of motor itself can not get effective recovery, does not therefore excavate the maximum capacity of electricity-thermal conversion.
The utility model content
The purpose of this utility model is to provide a kind of energy-conservation water-cooling permanent magnet frequency control three phase electric machine, solves the problem that prior motor noise heat energy big and motor heating itself does not make full use of.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of energy-conservation water-cooling permanent magnet frequency control three phase electric machine is made of body, motor core, cooling body, and body comprises casing, left end cap, right end cap, rotor, terminal box, variable-frequency governor, arbor, base, and the casing two ends are provided with left end cap and right end cap; Be embedded with permanent magnet on the rotor, rotor surface is provided with curved groove, and location and installation is on arbor; Variable-frequency governor is installed in the terminal box, and the downside of casing is provided with base; Cooling body is made up of motor, water inlet, delivery port, end cap etc., be covered with the motor water cooling cover in the outside of motor, and be provided with terminal box, put cooling water inlet and coolant outlet at motor water cooling in the outside, and be respectively equipped with end cap in both sides, the motor core is arranged in the cooling body cavity.
The beneficial effects of the utility model are: the motor rotor surface is provided with curved groove, can eliminate some harmonic waves harmful to motor, and power consumption, temperature rise and the noise of motor are reduced; Rotor adopts rare earth permanent-magnetic material, and magnetic field intensity is big, so its detent torque is big, starting current is little, speed-regulating range width; Both do not had copper loss on the rotor and had or not iron loss, its efficient ratio is with capacity adjustable frequency motor height; Motor utilizes recirculated water cooling principle, and the control electric machine temperature rise reduces the loss of electric machine, noise of motor, improves electric efficiency, has the energy-conserving and environment-protective meaning.
