Control system for brushless DC motor, includes Hall element to detect angular position of rotor and incorporates MOSFET, signal output circuit and temperature control circuit

摘要

The brushless DC motor (13) is fed with current via a reverse protection circuit (10c). It is connected to a control circuit (10) and a remote circuit for back EMF (10d). A Hall element (11) is used to detect the angular position of the rotor of the motor and is connected to the control circuit. The control circuit is connected a signal output unit (10a), also to a MOSFET (192), which is in turn connected to a temperature control circuit (10b).
