Embodiment Construction

[0025] The present invention will be further elaborated below in conjunction with embodiment.

[0026] As a clutch mechanism power stand-alone, figure 1 It is a three-dimensional diagram of a small redundant servo motor with double stators and double resolvers. In order to meet the requirements of the system for double stators and double resolvers, small size, low weight, and oil-immersed work, the magnetic circuit of the motor is reasonably designed, and the electromagnetic field and temperature field are limited. Meta-analysis research fully improves the electromagnetic utilization space, improves the torque density, speed range and short-term temperature resistance, and reduces the volume and weight of the motor. At the same time, effective structural design measures are taken to ensure the stability and reliability in the oil-immersed working environment.

[0027] The permanent magnet synchronous servo motor is composed of a housing 5, a rotor 14, a double stator 13, a do...

Abstract

The invention relates to a double-stator double-rotary-transformer small redundancy servo motor which comprises a rotor, double stators, double rotary transformers, an end cover assembly and an electric connector. The rotor is installed on a rotor shaft, and the surface of the rotor is sleeved with a metal sheath. The double stators are fixedly arranged on the same motor shell and share the rotorshaft; and the double rotary transformers are connected to the rotor shaft in series, are distributed at the tail end of the motor, are subjected to shaft end sealing by the end cover assembly, sharethe electric connector for detecting the position and speed of the rotor, and are respectively transmitted to an EHA driving controller and an EMA driving controller through the electric connector andan external cable. The EHA driving controller and the EMA driving controller can independently control the motor; and the end cover assembly is provided with an oil through hole, and the whole motorinner cavity is immersed in oil.

Description

technical field [0001] The invention relates to a small redundant servo motor with double stators and double resolvers, in particular to a small redundant servo motor for realizing the double redundancy switching function of the clutch mechanism of an integrated electric steering system. Background technique [0002] The small redundant servo motor with double stators and double resolvers (hereinafter referred to as the motor) is the core component of the power and control of the clutch mechanism of the integrated electric steering system. The motor drives the eccentric shaft sleeve structure to provide power for the clutch quantitative pump. The drive controllers are EHA drive controller and EMA drive controller respectively. Both sets of controllers can independently control the motor, so as to realize the dual redundant switching function of the main steering gear clutch of the integrated electric steering system. Correspondingly, how to solve the reliable operation of th...
