The invention discloses a hollow cup servo motor system, comprising a casing provided with a first end cover, a second end cover and a third end cover. A stator is mounted between the first end coverand the second end cover, a rotor rotated by a rotating magnetic field is mounted in the middle of the stator, and the rotor outputs a torque. A servo position sensing module is mounted at one end ofthe rotor extending out the second end cover, and the servo position sensing module is used for detecting the position information of the rotor in real time. A servo drive board is mounted between thesecond end cover and the third end cover, the servo drive board comprises a servo control module and a servo power module, the servo control module is electrically connected with the servo power module, and the servo control module comprises an analysis module capable of sensing the servo position sensing module. By directly integrating the servo drive board to the tail of a motor, the space is saved, the efficiency of the motor is improved, and the safety is improved.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a hollow cup servo motor system. Background technique [0002] The hollow cup servo motor system is a high-efficiency energy conversion device, which is widely used in daily production and life. With the rapid development of existing products, the requirements for power devices are getting higher and higher, but there are many cables for connection between the motor and the control unit of the existing hollow cup servo motor system, such as power cables, Signal cables for transmitting signals between sensors. Due to the existence of the power cable, there will be inevitable loss on the power cable, resulting in a decrease in the efficiency of the motor, and the connection of the encoder signal cable between the motor and the control unit will also increase the failure rate of the system. Contents of the invention [0003] The object of the present invention is to provide a hol...
