Motor Control Guide 2 Texas Instruments 3Q 2008
OVERVIEW
TI provides a broad range of analog products, digital controllers and software to precisely control the position, velocity and
torque of mechanical drives. This guide provides motor control and drive solutions for small drives including solenoids,
DC or brushless DC and steppers; and for larger drives such as AC-open loop (inverters) and closed loop (servo) systems
that utilize much higher voltages, typically hundreds of volts.
