Problems solved by technology

[0003] The disadvantage of adding a gearbox is that it is large in size and heavy in weight, which reduces system efficiency and causes environmental noise pollution on site; while increasing the number of pole pairs increases the technical difficulty of offline and wiring in the case of three-phase or multi-phase, the process The cost has risen sharply, and the upper limit of the number of pole pairs is strictly limited by the structural size. Under the same torque condition, the power of the motor needs to be greatly increased

Abstract

The invention provides a motor stator, a motor, a linear motor stator and a linear motor. The motor includes n coaxial motor units. The motor unit includes a rotor unit and a stator unit. The numbersof rotor magnetic poles and stator poles are both n. A mechanical deflection angle is arranged between adjacent motor units. The mechanical deflection angle a=360 / (n*m) degrees. The polarities of theadjacent rotor magnetic poles are opposite; a Hall element is arranged between adjacent stator magnetic poles. The linear motor comprises n motor units arranged side by side along the Y-axis direction, wherein the motor unit comprises a rotor unit and a stator unit. The number of the stator magnetic poles is m. The number of the rotor magnetic poles is z. A Hall element is arranged on the stator unit every z-1 stator magnetic poles; the stator magnetic pole has a distance d. The rotor magnetic pole has a distance d. An offset h is arranged between adjacent motor units and the offset h=d / n. Both the motor and the linear motor have the characteristics of direct drive, low speed and large load output.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor stator, a motor, a linear motor stator and a linear motor. Background technique [0002] At present, there are two types of motors: asynchronous motor and synchronous motor. The stator of the motor is mostly designed according to the principle of three-phase or multi-phase rotating magnetic field, and the rotor is realized by the principle of permanent magnet, induction cage or reluctance. In actual use, if it is necessary to obtain low-speed high-torque output, it is necessary to increase the reduction box, or increase the number of pole pairs. [0003] The disadvantage of adding a gearbox is that it is large in size and heavy in weight, which reduces system efficiency and causes environmental noise pollution on site; while increasing the number of pole pairs increases the technical difficulty of offline and wiring in the case of three-phase or multi-phase, the process The cost ha...
