Description
Technical Field
The invention relates to the field of driving motors, in particular to a multi-contact array stator of an automobile motor.
Background
When the vehicle speed is at a low speed, if a high-speed motor is adopted, the motor torque is insufficient, and the motor torque is not suitable for accelerating an automobile. In the prior art, two sets of motor stator windings are adopted to work respectively to realize the switching before a high-speed motor and a low-speed motor, and the defect is that two sets of windings are needed to waste materials.
For the automobile motor adopting one set of windings, the windings of the automobile motor are fixed, so that the stator windings of the automobile motor are not easy to change. Once the stator of the motor is made, its parameters such as winding form, number of turns in parallel, etc. are determined.
Disclosure of Invention

The switching device aims to solve the switching problem of the existing motor windings of the automobile, namely, the switching of a high-speed motor and a low-speed motor can be realized only by one set of windings.
In order to achieve the above purpose, the invention provides a multi-contact array stator of an automobile motor, which comprises a stator core provided with N slots, wherein a first outgoing line and a second outgoing line are arranged in each slot, the first outgoing lines of all slots form a first u-phase winding, a second v-phase winding and a third w-phase winding, and the second outgoing lines of all slots form a fourth u-phase winding, a fifth v-phase winding and a sixth w-phase winding;

In the technical scheme, the parallel switch and the series switch are connected with the outgoing lines to form a stator winding, on one hand, when the series switch is closed and the parallel switch is opened, the first outgoing line and the second outgoing line form a winding with the number of turns of 2 of the array stator, and the motor is equivalent to a motor with lower relative rotating speed and larger torque to operate. On the other hand, when the series switch is opened and the parallel switch is closed, the first outgoing line and the second outgoing line form windings with the number of turns of 1 and the number of parallel connections of 2 of the array stator, and the motor runs corresponding to a high-speed motor with higher rotating speed and relatively smaller torque. In the technical scheme, the switchable array stator is also beneficial to motor energy conservation, the high-speed motor and the low-speed motor can be effectively switched, and the service efficiency of the motor is effectively improved.
Further, the first parallel switch, the second parallel switch, the third parallel switch, the fourth parallel switch, the fifth parallel switch and the sixth parallel switch form a six-pole double-throw switch; the first series switch, the second series switch and the third series switch form a three-pole double-throw switch.
In the technical scheme, a six-pole double-throw switch and a three-pole double-throw switch are adopted to switch windings of an array stator, so that the switching of a high-speed motor and a low-speed motor is realized. When the three-pole double-throw switch is turned on, the six-pole double-throw switch is turned off, the number of turns of the array stator is 2, and the motor is equivalent to a motor with lower relative rotation speed and larger torque to operate. When the three-pole double-throw switch is turned off and the six-pole double-throw switch is turned on, the number of turns of the array stator is 1, the number of parallel connection is 2, and the motor is equivalent to a high-speed motor with higher rotating speed and relatively smaller torque to operate. In the technical scheme, the multi-pole multi-throw switch is adopted, so that the stability in the motor switching process is facilitated, and meanwhile, the switchable array stator is also beneficial to energy conservation of the motor.

In the technical scheme, the parallel switch and the series switch are digital switches, and the controller controls the parallel switch and the series switch to be turned on or turned off. When the series switch is turned on and the parallel switch is turned off, the number of turns of the array stator is 2, and the motor is equivalent to a motor with lower relative rotating speed and larger torque to operate. When the series switch is turned off, the parallel switch is turned on, the number of turns of the array stator is 1, the number of parallel connection is 2, and the motor runs corresponding to a high-speed motor with higher rotating speed and relatively smaller torque. In the technical scheme, the controller controls the photoelectric coupling tube to change the state of the array stator winding, so that the automatic switching of the high-speed motor and the low-speed motor is realized, the switching speed is high, and the energy conservation of the motor is facilitated.
