Method for excitation and recuperation of DC motor and DC motor with recuperation

摘要

A DC motor with regeneration, comprising a rotor (3) with an output shaft (11) for transmitting torque to the machinery or power equipment consists of a stator (9) which is formed by a n-member set of series-driven stator excitation coils (1), n- and a n-member array of ferrite cores (2) arranged such that one stator excitation coil (1) and one stator induction coil (14) are arranged at each ferrite core (2). It further comprises a rotor (3) having an n-member permanent magnet assembly (4) mounted on its circumference with the same polarity orientation. The first stator excitation coil (1) is connected to the positive supply terminal (+ UB) and the last stator excitation coil (1) is connected to the negative supply terminal (-UB) via a control circuit with control / switching circuit (6). The first stator induction coil (14) is connected to the positive power terminal (+ UB) via the recovery line (8) and the last stator inductor (14) is connected to the negative power terminal (-UB).
