Brushless motors are ubiquitous in RC applications and robotics, but are usually driven with low-cost motor controllers that have to be controlled with RC-style PWM signals and don’t allow for ...

Flexible motor speed control is achieved by using either an external PWM signal or DC voltage, or a voltage derived from a thermistor network. Both motors are able to adjust the duty cycle of the full ...

To accomplish this an RC system was used with an MD22 h-bridge driver and a picoUPS. The MD22 is a neat motor control board which can take the PWM signals from the radio controller and use this to ...
