Embodiment Construction

[0011] Referring to Fig. 2, the AC permanent magnet synchronous outer rotor type torque motor of the present invention is illustrated, wherein the motor stator cover 3 comprising silicon steel sheets and coil windings is on the inner cooling sleeve 4 of the stator, and a spiral cooling groove is arranged on the inner cooling sleeve 4 of the stator , for effective cooling of the motor stator in order to ensure greater torque. The rotor 2 whose inner wall is a permanent magnet patch 6 is placed on the outer ring of the stator 3 to form an outer rotor structure. In addition, since the rotor of the torque motor is located outside, the brake mechanism 1 for locking the outer rotor 2 located outside can be conveniently designed.

[0012] The AC permanent magnet synchronous outer rotor type torque motor of the present invention, because the outer rotor 2 is directly connected with the executive component, the intermediate transmission component is omitted, thereby achieving the effec...

Abstract

The invention discloses one alternating permanent simultaneous outer rotor torque motor, which comprises the following parts: ring rotor composed of sand steel slice and coil set inside and rotor outside the rotor with inner wall added with slice, brake structure outside rotor and inner ring cooling cover. The invention has higher output torque to realize direct connection between outer rotor and execution part.

Description

technical field [0001] The present invention relates to a motor, more specifically, to an outer rotor motor. Background technique [0002] Most existing torque motors adopt an inner rotor structure, that is, a structure in which the rotor is inside and the stator is outside. As shown in Figure 2, a typical torque motor with an inner rotor structure includes an inner motor rotor 3', a motor stator 2' outside the rotor 3', and a stator cooling jacket 1' located outside the stator 3' for cooling. [0003] At present, enterprises or research institutes at home and abroad, such as Germany's Siemens, are developing torque motors with inner rotor structures. But the problem is that the torque motor with inner rotor structure is used in the occasion of direct drive, especially on the executive parts of the machine tool such as the turntable and the pendulum milling head. Larger volume. In addition, the brake mechanism of the inner rotor of the inner rotor torque motor has a compl...
