Motor for Direct Drive of Electric Wheelchair

摘要

Described in the paper is analysis of properties of synchronous motor with outer permanent magnets rotor. The motor, having an atypical construction, is powered by low voltage from a three phase frequency converter. It is suitable as a drive unit for direct power drives of small electric vehicles and electric wheelchairs. Theoretical analysis of the synchronous motor with outer permanent magnets rotor starts with the air gap space configuration. The present paper describes the main results from open-circuit and load simulation. The section of paper describes the mechanical construction of prototype of the synchronous machine. Experimental results of measurements of the machine prototype in the generatoric and motoric mode are described. Experimental measurements verified stability of the motor parameters at its loading.
