Motor with attaching position detection and bidirectional power output function

Abstract

The invention relates to a motor with an attaching position detection and bidirectional power output function. The motor at least comprises a motor case, a stator which is annularly fixed on the internal periphery of the motor case, a rotor with a spindle which is fixedly connected in the middle of the rotor, and a base on which a brush set is arranged. The front end of the spindle which is fixedly connected in the middle of the rotor stretches out of the motor case to drive one group of other devices to rotate. The rear end of the spindle particularly stretches out of the base. At least a motor rear cover, an interface plate, a circuit board on which a magnetic sensor is arranged, a magnet with poles sensed by the magnetic sensor on the circuit board for position detection, and a detection cover are sheathed on the periphery of the spindle. Finally, the rear end of the spindle is enabled to stretch out of the detection cover and can drive the other group of other devices to rotate. Therefore, the structure of the motor is simple and convenient to assemble; when the motor rotates, the two ends of the spindle can be used as power output ends to drive other devices to rotate; and the efficiencies such as rotating direction, rotating speed and revolutions of the spindle during rotation are measured.

Description

technical field [0001] The present invention relates to a motor, especially to a motor in operation. In particular, both ends of the mandrel fixed on the rotor of the motor can be used as power output to drive other devices to rotate, and the movement of the mandrel during the operation is measured. Research inventions made on steering, rotational speed and number of revolutions. Background technique [0002] General small motor 2 (refers to the motor with a diameter less than 50mm), please refer to Figure 1 to Figure 5 As shown, it mainly includes: [0003] A motor housing 21 is a cylindrical housing with a hollow interior, a through hole 211 is formed in the center of the front end, and a bearing 212 is fixed in the through hole 211 . [0004] A stator 22 includes a plurality of magnets 221 and magnet spacers 222 and is fixed on the inner periphery of the motor housing 21 . [0005] A rotor 23 comprises: a silicon steel sheet 231, a coil 232 wound on the silicon steel s...

Problems solved by technology

[0008] Yet above-mentioned existing small motor 2, the mandrel 233 of its rotor 23, its rear end 2332 sleeve is fixed in the bearing 244 that is located in the center positioning groove 243 of base 24, solid only relies on the front end 2331 of mandrel 233 to 1 It can only provide to drive other devices to rotate, that is, the whole small motor 2 can only provide to drive other devices to rotate by virtue of the front end 2331 of the mandrel 233, as for the regret that the rear end 2332 of the mandrel 233 cannot provide to drive other devices to rotate, And, the whole small motor 2 is in the running process, and it also only simply provides the front end 2331 of the mandrel 233 of the rotor 23 to drive other devices to rotate. Counterclockwise? What is its speed? It is impossible to know, but it must be measured by other instruments, which causes inconvenience and needs to be improved.
