Abstract

The invention relates to a motor and a vehicle with the motor. The motor comprises a central rotating shaft and a motor casing; and the motor further comprises a speed sensing device, the speed sensing device comprises a speed sensor and indexing teeth that match the speed sensor, the indexing teeth are placed on the central rotating shaft, and the speed sensor is mounted on the motor casing. The speed sensing device is integrated to the motor, the central rotating shaft of the motor is provided with the indexing teeth, the speed sensor is mounted on the motor casing, a heavy indexing gear mechanism is abandoned, the problem that maintenance is inconvenient due to the fact that the speed sensing device is mounted in an axle in the prior art is solved, installation is convenient, the structure is simplified, convenience is provided for arrangement of the whole vehicle, and the integrated degree of components is improved so that the vehicle is lighter.

Description

technical field [0001] The invention relates to a motor and a vehicle using the motor. Background technique [0002] Currently more commonly used motors for new energy vehicles, such as figure 1 As shown, the motor includes a central shaft 1, a junction box 2, a stator assembly 3, a rotor assembly 4, a motor housing 5 and a rotational speed signal measuring device, wherein the rotational speed signal measuring device is a resolver 6, and the motor housing 5 includes a front cover and The rear end cover, the rotary transformer 6 is fixed on the rear end cover. [0003] Such as figure 2 As shown, the speed sensor device independent of the motor includes a speed sensor 8 and an indexing gear mechanism 9 arranged up and down that match each other. Since the speed pulse signal of the rotating shaft will be collected during use, the speed sensor device is generally installed in the axle, the indexing gear mechanism 9 is fixedly connected with the central rotating shaft, and th...
