  • Method of and electronic circuit for starting a reluctance motor and reluctance motor provided with such an electronic circuit
    Patent number: 4795953
    Abstract: A reluctance motor comprises a stator (S) provided with coils (W1, W2), and a rotor (R). The rotor R has pairs of positions of stable equilibrium and pairs of positions of unstable equilibrium. The reluctance motor is started by first bringing the rotor into a first position of stable equilibrium (.theta.=-.theta.ms) by means of a first energizing current and subsequently rotating it towards a second (.theta.=0) of stable equilibrium by means of a second energizing current.
