IC DELIVERS FAST PWM GENERATION FOR MOTOR CONTROL APPLICATIONS
40 kHz PWM output lowers torque ripple and improves smoothness.
Lincoln, MA — Performance Motion Devices, Inc. (PMD) announces the release of the MC73110 Motor Control IC with faster 40kHz PWM (pulse width modulated) waveform generation. This compact, single-axis IC provides advanced, fully-digital velocity and torque control of brushless DC motors. Using the MC73110, only a MOSFET or IGBT triple half-bridge is needed to create a complete intelligent motor controller.
 The MC73110 operates in one of three modes: internal velocity profile mode, velocity mode with an external command signal, and torque mode with an external command signal. It provides software-programmable velocity and current loops, six-step and sinusoidal commutation, analog or digital command input, profile generation, and digital current loop. It can be operated as a stand-alone intelligent motion IC, or via serial commands as a programmable axis controller. Additional functions of the MC73110 include PI current loop compensation, trajectory generation, commutation, velocity loop, encoder input, and Hall sensor input.
The MC73110 is ideal for low-cost brushless motor amplifiers. It can be used in applications such as medical automation, centrifuges, tape drives, machine tools, scientific instrumentation, semiconductor equipment, HVAC, pumps and compressors, and general automation. The new higher-speed PWM output is ideal for low inductance motors, and with applications that require high motor velocity or high acceleration.
