Abstract

A drive circuit for a brushless DC motor controls at least one of a number of possible operation features of the motor. The drive circuit includes a driver stage for providing a current for a stator coil and varies which of the number of possible operation features of the motor are controlled. The operation features of the motor include inrush current limit control, PWM speed control, analog speed control, detecting a locked rotor condition, setting an alarm following detection of the locked rotor condition, restarting the motor following the locked rotor condition, detecting a low speed condition, and setting an alarm following detection of the low speed condition. Some of the operation features of the motor utilize at least one parameter that defines the desired operation of the feature. The drive circuit further varies the parameters of the operation features without changing the physical configuration of the brushless DC motor.
