3-phase BLDC Motor Control
Demand for brushless DC (BLDC) motors is growing,
fuelled by a combination of their inherent reliability and dynamic
response, commercial, environmental and legislative pressure for
improved efficiencies, and ongoing decreases in the cost of BLDC
technology.
Featuring on-chip
PWM support for optimum efficiency and sine wave options to minimise
acoustic and electrical noise, Toshiba's comprehensive range of IC
drivers and controllers for BLDC motors provides for sensor-based and
sensorless control and offers peak output currents from 2mA to 2.5A. For
ultimate integration levels, Toshiba's TB6581 inverter/driver can
provide a complete 230VAC/1A sinewave BLDC driver in a single package.
TB6582 is Toshiba's first controller providing a full sensorless sine wave PWM motor control.
