electrical drive
Electric drive is an electromechanical system (mechatronic system) intended to set into motion technological equipment. It consists of an electric motor (motors), a transfer mechanism, an electrical energy converter, and a control system. The control system consists of a microcontroller with data connection interfaces, data channels (data network), sensors and actuators. A generalized structure of […]
power factor improvement
Improving the PF can maximize current-carrying capacity, improve voltage to equipment, reduce power losses, and lower electric bills. The simplest way to improve power factor is to add PF correction capacitors to the electrical system. PF correction capacitors act as reactive current generators.

soft start motor
A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the power train and electric current surge of the motor during start-up A soft starter can eliminate these problems by gradually increasing voltage to the motor terminals during startup, providing a controlled ramp-up to full […]

bidirectional motor
One of the simplest ways to get a motor to turn in both directions is by using a double-pole, double-throw (DPDT) relay. Along with the relay, this hookup requires two transistors and two Stamp pins, one for on/off control and the other for direction control. The M54544AL is a semiconductor integrated circuit that is capable […]
