Problems solved by technology

[0003] The motors in the prior art usually use a reducer to increase the torque, but the motor with this structure has high cost, low efficiency and high noise due to the reducer, so the cost of the entire motor is high, the noise is large, and due to the deceleration The existence of the motor causes the weight and volume of the motor itself to increase, so it is unfavorable to apply such a motor to a robot, especially a robot directly driven by a motor

Embodiment 1

[0047] In the field of robotics, it is necessary to use electric motors (also known as motors) to drive the movement of each joint. However, because the movement of robots, especially industrial robots, usually need to bear a certain load, high-torque motors are required to meet the requirements of industrial robots. The motors in the prior art usually increase the torque by using a reducer, but on the one hand, the motor with this structure has high cost and high noise due to the reducer, so the cost of the entire motor is high and the noise is large, and because the reducer Existence causes the weight and volume of the motor itself to increase, so it is unfavorable to apply such a motor to a robot, especially a robot directly driven by the motor.

[0048] In order to solve the above problems, the present invention provides a high-torque motor. At least part of the stator magnetic-conducting part and the mover magnetic-conducting part include a high-flux magnetic-conducting pa...

Embodiment 2

[0168] Embodiment 2 of the present invention also provides a robot including the high-torque motor described in Embodiment 1.

[0169] As described in Embodiment 1, the greater the magnetic flux density, the greater the iron loss will be. When the motor moves at a high speed (such as in the field of automobile driving), excessive iron loss will be generated per unit time, resulting in serious heating of the motor. Then seriously affect the performance of the motor and even cause damage to the motor. However, the motor described in the embodiment of the present invention is suitable for use in the field of mainly low-speed operation (such as: robot). Since the motor only occasionally moves at high speed, it is not necessary to consider the iron loss factor, and a high magnetic flux density motor can be used. Material.

Abstract

The invention relates to a high-torque motor comprising a mover and a stator assembly. The mover and the stator include magnetic conductive parts; a plurality of permanent magnets are arranged at the stator and / or mover; and a gap is formed between the mover and the stator. At least the parts of the magnetic conductive parts are made of high-magnetic flux density materials. According to the motor, at least the parts of the stator magnetic conductive part and the mover magnetic conductive part include high-magnetic flux density magnetic-conductive parts; and the torque is improved by increasing the magnetic field intensity, so that problems caused by utilization of a reducer by the motor can be solved.
