Abstract

The invention discloses an energy-saving servo motor which comprises a case, a stator assembly and a rotor assembly. The rotor assembly comprises a motor shaft and a rotor iron core, the rotor iron core is fixedly sleeved on the motor shaft, a plurality of silicon steel sheets are laminated to form the rotor iron core, a plurality of steel magnets made of neodymium, iron and boron materials are mounted on the rotor iron core, T-shaped lugs which are distributed circumferentially are arranged on the circumferential surfaces of the silicon steel sheets in the middle of the rotor iron core, the quantity of the T-shaped lugs is identical to that of the steel magnets, the lugs on the silicon steel sheets are laminated to form clamp grooves, and the steel magnets can be embedded into the clamp grooves. Compared with the prior art, the energy-saving servo motor has the advantages that the steel magnets made of the neodymium, iron and boron materials are mounted on the rotor iron core of a rotor of the servo motor, excitation windings are omitted, the neodymium, iron and boron steel magnets are superior in magnetic properties such as high magnetic energy products and high coercivity, the lengths of air gaps can be maximized owing to the high coercivity of the materials, and accordingly an energy-saving effect of the servo motor is improved by 20% as compared with the traditional ferrite motor and other types of motors, and is excellent.

Description

technical field

[0001] The invention belongs to the technical field of motors, in particular, the invention relates to an energy-saving servo motor. Background technique

[0002] At present, the most common motor used on sewing machines is the clutch motor. Due to its low cost advantage, the clutch motor's dominance has been difficult to be shaken by other motors. Because the power of the clutch motor is transmitted by the clutch of the clutch, no matter whether it is sewing or not, the motor is always running, so the no-load time of the motor often exceeds the working time, and the idle consumption is very large. On the other hand, since the clutch motor is an AC asynchronous motor, and the output efficiency of the AC asynchronous motor itself is low, the efficiency is greatly reduced when the torque is transmitted to the sewing machine through the friction clutch, so the output power of the entire system is very low and the efficiency is very low. In addition to high ener...

Embodiment Construction

[0027] Such as figure 1 Shown is an energy-saving servo motor of the present invention, including a casing 1 , a stator assembly 2 and a rotor assembly 3 . Such as figure 2 with image 3 As shown, the rotor assembly 3 includes a motor shaft 31 and a rotor core 32 sleeved and fixed on the motor shaft 31. The rotor core 32 is formed by laminating several silicon steel sheets. The rotor assembly 3 has no field winding. A plurality of magnetic steels 33 made of NdFeB materials are installed on it, and the magnetic steels 33 are in the shape of tiles. The silicon steel sheet in the middle part of the rotor core 32 has 33 magnets distributed along the circumferential direction on the outer peripheral surface. There are identical T-shaped bumps 34, and the bumps 34 protrude outward along the radial direction of the silicon steel sheet. The bumps 34 on all the silicon steel sheets in the middle are stacked together to form a draw-in groove equal in number to the magnetic steel 33....
