Abstract
PURPOSE: To simplify a position detection circuit for a commutatorless motor, by using an integrated circuit comprising a Hall element, a pre-amplifier and a Schmidt circuit.
CONSTITUTION: Motor coils 3∼5 are located at an electric angular spacing of 120° inside permanent magnet rotors 1, 2. Position detectors 6, 7, 8 are provided for the coils. Each position detector is made of the integrated circuit comprising the Hall element 6a, the pre-amplifier 6b and the Schmidt circuit 6c. Since no amplifier is used separately from the Hall element, the position detection circuit is simplified.
