Abstract
The utility model discloses a multi-phase drive motor winding applied to a vehicle. The multi-phase drive motor winding applied to the vehicle comprises a first three-phase star type winding (1) and a second three-phase star type winding (2), wherein the first three-phase star type winding (1) and the second three-phase star type winding (2) are arranged in a stator slot of a drive motor. The angular difference between the first three-phase star type winding (1) and the second three-phase star type winding (2) is 30 degrees. The starting ends of A1, B1 and C1 of the first three-phase star type winding (1) are short-circuited to form the midpoint of the first three-phase star type winding (1). The starting ends of A2, B2 and C2 of the second three-phase star type winding (2) are short-circuited to form the midpoint of the second three-phase star type winding (2). The tail ends of a1, b1 and c1 of the first three-phase star type winding (1) and the tail ends of a2, b2 and c2 of the second three-phase star type winding (2) are respectively led out through wires. According to the utility model, the multi-phase drive motor winding applied to the vehicle has the advantages of low control cost, low operation temperature and small vibration and noise.
Description
Technical field
The utility model relates to a kind of motor windings, is specifically related to a kind of automobile-used heterogeneous drive motors winding.
Background technology
Continuous increase along with the drive motors power demand; For requiring the Application of frequency control of motor speed occasion, the three-phase drive motor is realized through low-voltage, high-current or high pressure low current, but no matter is low pressure or high pressure; The problem that all has control system type selecting difficulty, the control system cost is high.And three-phase drive motor temperature in running is high, and vibration and noise are big.
The utility model content
The purpose of the utility model promptly is to overcome the deficiency of prior art, provides a kind of and controls cost lowly, and operating temperature is low, vibration and the little automobile-used heterogeneous drive motors winding of noise.
The purpose of the utility model realizes through following technical scheme:
Automobile-used heterogeneous drive motors winding; It comprises the three-phase star winding one and three-phase star winding two that is arranged in the drive motors stator slot; 30 ° of the angle mutual deviations of three-phase star winding one and three-phase star winding 2; A termination A1, B1 and the C1 short circuit of three-phase star winding one are the mid point of three-phase star winding one; A termination A2, B2 and the C2 short circuit of three-phase star winding two are the mid point of three-phase star winding two, and tail end head a1, b1 and the c1 of three-phase star winding one and tail end head a2, b2 and the c2 of three-phase star winding two draw through lead respectively;
In the six phase winding, wherein the coil on two windings is few circle coil, and the coil on all the other four windings is a multiturn coil, and the number of turn of multiturn coil is the twice of few circle coil turn.
The advantage of the utility model is:
1. adopt the six phase winding, can reduce the electric current of the every phase of drive motors, thereby can adopt the low relatively power tube of grade to control, reduced the cost of controller;
2. adopt the six phase winding, the temperature rise of drive motors is obviously reduced, vibration and noise obviously reduce.
