Flat copper wire formed stator coil high-reluctance torque outer rotor type permanent magnet drive motor

Abstract

The invention discloses a flat copper wire formed stator coil high-reluctance torque outer rotor type permanent magnet drive motor. The permanent magnet drive motor comprises a coupler shaft, whereinthe left and right sides of the coupler shaft are connected with a front end cover and a double-screw water channel ring respectively; a rear bearing is fixed onto the double-screw water channel ring;the double-screw water channel ring is matched with a water channel outer ring to form a double-screw water channel; the water channel outer ring is connected with an inner stator iron core; the coupler shaft is provided with an outer rotor magnet yoke fixed barrel; a self-buckle type outer rotor iron core is arranged on the inner surface of the outer rotor magnet yoke fixed barrel; and a plurality of magnetic steel is arranged on the self-buckle type outer rotor iron core in an inserted manner. By using the distribution of inverted V-shaped magnetic steel, the permanent magnet drive motor has the characteristic of high reluctance torque; a flat copper formed coil is used, a stator is an open slot, and the utilization rate of the slot is improved by 25% compared with that of a circular copper wire; a machine hand can be used for inserting winding; the efficiency of the motor can be improved by using more copper and few magnetic steel, the cost is reduced, the power density and torquedensity are improved, and the cost performance is higher; and the double-screw water channel has the advantages of low water resistance and high heat dissipation capacity.

Description

technical field [0001] The invention relates to the field of energy equipment, in particular to a flat copper wire formed stator coil high reluctance torque outer rotor permanent magnet drive motor. Background technique [0002] Permanent magnet motors have the advantages of high efficiency, high power density, large power factor, large starting torque, wide speed range, etc., and have gradually replaced induction motors and switched reluctance motors, and are increasingly being used in many fields of industrial production and daily life. Wide range of applications. However, since the permanent magnet is installed on the rotor, it is difficult to dissipate heat. The temperature rise caused by the permanent magnet may cause irreversible demagnetization of the permanent magnet, which limits the output of the motor and increases the potential safety hazard. [0003] At present, the stator core of the permanent magnet motor is closed slotted, which is inconvenient for the robot...

Problems solved by technology

However, the permanent magnet is installed on the rotor, and it is difficult to dissipate heat. The temperature rise caused may cause irreversible demagnetization of the permanent magnet, which limits the output of the motor and increases the potential safety hazard.

[0003] At present, the stator core of the permanent magnet motor is closed slotted, which is inconvenient for the robot to operate; the magnetic steel is arranged in a straight line, and the energy conversion rate is low, and the rotor punching plate adopts the entire ring structure, which wastes a lot of materials
