This lets them be used in applications needing dynamic behavior and fast responses from the motor. Using PWM allows precise current control in the windings.

QPT introduced MicroDyno, a low-voltage motor drive testbed that demonstrates the performance of ultra-high frequency ...

It’s an excellent way to learn about both PWM motor control and the use of 555 timers, all with a very low parts cost and readily available components. We’ve seen such setups before, used as ...

Freescale's MC56F82xx targets motor and power control applications with a 60MHz 56800E DSC core and NanoEdge PWMs.

QPT has unveiled MicroDyno, what it describes as a breakthrough low-voltage motor drive test platform which demonstrates the ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points ...
