How to Control BLDC Motors

Brushed motors are simple and effective but only offer speed control through change in voltage. Brushless motors offer a greater degree of control through a small solid-state computer. Instead of carbon brushes powering the spinning rotor, an internal 3-phase inverter and electronic control are used. How Does a BLDC Motor Work? All electric motors convert…

Motor Mouth: Obtain Accuracy and Position Control with Stepper Motors

Operation A step motor is a motor type with a permanent magnet rotor and a stator wound with two independent windings. By alternating the direction of current flow through these windings, the motor will move in discrete “steps”. The size of the step varies with the construction of the motor. The commonly available range is…
