Title:
MULTI-POLE FEW-SLOT UNITIZED PERMANENT MAGNET HUB MOTOR AND COORDINATED CONTROL SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/040742
Kind Code:
A1
Abstract:
Disclosed are a multi-pole few-slot unitized permanent magnet hub motor and a coordinated control system and method. The motor is composed of N same motor units evenly distributed in the circumferential direction of a radial cross section, each 1/N outer rotor is divided in the axial direction into M rotor sections which are the same, and the M rotor sections are arranged as sequentially rotating one mechanical dislocation angle in the same rotating direction. A constant torque area is divided into a first area and a second area, and a constant power area is divided into a third area to an eighth area. The control system comprises two control modules, each control module is composed of a power electronic switch, a DSP controller and an inverter which are sequentially connected in series, and input ends of two power electronic switches are respectively connected to an output end of a battery. An output end of each inverter is separately connected to N/2 winding electronic switches, one winding electronic switch controls a centralized winding in one motor unit to turn on and off, and mutually independent winding electronic switches implement independent control of the motor unit, thereby improving motor control freedom and increasing operating efficiency.
