ABSTRACT:
A motor having a stationary assembly including a winding and a rotatable assembly in magnetic coupling relation to the stationary assembly. A bridge circuit for use in driving the motor has upper and lower power switches connected between the winding and the upper and lower rails, respectively, of a power supply link. Each of the lower switches corresponds to one of the upper switches and each of the switches has a conducting state and a nonconducting state. The motor also has a control circuit for generating a motor control signal to control the switches. The lower switches are receiving and responsive to the motor control signal. A drive circuit drives the upper switches in response to the state of the lower switches to selectively connect the rails of the power supply link to the winding. As such, the winding is energized to produce an electromagnetic field for rotating the rotatable assembly relative to the stationary assembly. The drive circuit controls the upper switches to provide a delay interval between the conducting states of the corresponding upper and lower switches thereby reducing shoot-through currents.
