Abstract

The invention discloses a large-current low-voltage servo motor which comprises a machine shell, and an installation space is formed in the machine shell. A stator assembly is included and comprises a stator iron core arranged in the installation space, the inner circumferential surface of the stator iron core is provided with a stator groove for embedding a coil, a coil winding is embedded in the stator groove, and the coil winding is a three-phase coil winding; and a rotor assembly is included and comprises a rotor iron core, the stator iron core sleeves the outer peripheral surface of the rotor iron core, magnetic steel is adsorbed on the outer peripheral surface of the rotor iron core, the magnetic steel is arc-shaped, the magnetic steel is provided with an inner arc surface and an outer arc surface, the inner arc surface and the outer arc surface are eccentrically arranged, the number of the magnetic steel is multiple, and the multiple magnetic steel is distributed according to an N-S polarity alternating sequence. The invention provides a large-current low-voltage servo motor which solves the technical problem that an existing motor is poor in stability during low-speed operation.

Description

technical field [0001] The invention relates to the field of servo motors, in particular to a high-current low-voltage servo motor. Background technique [0002] With the rapid development of information technology, more convenient and efficient transmission methods are required in the field of automation, and the transmission system powered by batteries can greatly improve the flexibility and adaptability of the transmission system. Therefore, the demand for low-voltage servo motors is coming one after another. [0003] Low-voltage servo motors include permanent magnet synchronous motors and excitation motors. Permanent magnet synchronous motors are new types of motors developed in recent years, but the existing permanent magnet synchronous motors are not stable and accurate at low speeds. Contents of the invention [0004] The main purpose of the present invention is to provide a high-current low-voltage servo motor, which aims to solve the technical problem of poor stab...
