T Series Synchronous Motor

General brief

T series synchronous motor is the series of products that are well developed on the basis of induction motor, and it requires unavailability of corrosive gases of acid and alkaline, etc. in the environments; the rated power factor is 0.9 (leading).

T series synchronous motor has utilized the computer for optimized design in terms of design, and employed new materials and new process, so it can meet all kinds of requirements of users and it has characteristics of reliable performance, small temperature scope, small consumption, high efficiency, small vibration, huge high dynamic torque, simple structure and easy maintenance, etc.

T series synchronous motor can be used for driving compressor, crusher, ball grinder, rolling mill, blower, water pump and other general machines.

Construction Description

There are all kinds of structural modes of synchronous motor: besides the general twin-bearing block structure, there are the fully-mounted, shaft-free and bearing block-free structure and semi-mounted and single bearing block structure; the movable stator structure; safety structure of slip ring with protective cover and positive draft; the round and box structure in which the bearing may bear the twin axial thrust and may run both forward and backward; automatic aeration-cooling and horizontal and vertical installation; the thyristor excitation structure with slip-ring and brush as well as the excitation structure without brush. The voltage levels include 380V, 3KV, 6KV and 10KV, etc. The protection modes of motor include multiple protection modes from IP00 to IP54.

The frame, end cover and bottom plate of synchronous motor are made of steel plate. Both the stator and bearing are equipped with thermometric parts which may monitor the motor temperature. The rotor employs the salient pole, and the two ends of magnetic yoke are equipped with fans, and the cool wind enters the inside of stator core from end covers at two ends, goes into the ventilating slot through the stator and goes out from the outlet of frame, so it has the good cooling effect. There are also modes of pipe and semi-pipe ventilation, air-water cooling and air-air cooling etc.

The bearings include the end sliding bearing, base-type sliding bearing (circulating cooling of pressure oi), and there are also the end cover rolling bearing (grease lubrication) etc.
