ABSTRACT:
A general purpose or universal motor control is constructed as integrated circuit using a plurality of state machines and memories. The specific characteristics of a motor are programmed into a programmable "features" memory. A lookup table contains parameters for operating the motor that are accessed as a function of the features. The features memory and the lookup table may be programmed and tested through a communications state machine. External and internal pulse width modulation is provided along with dynamic braking as options that are utilized by the state machines depending upon the features. A multiplexer acts a switch between the state machines, the memories and the motor drive.
