Every motor needs a way to transmit electricity to the windings, while every generator needs a way to extract electricity from the windings. This can be as simple as a wall plug connected directly to a single-phase motor, or leads to a battery for a DC motor. More often, especially in the case of polyphase windings, we need to have power electronics. The purpose of power electronics is to convert power from a common supply to a supply that will turn a motor, or to take the power created when a motor is turned as a generator and store it in a battery.

Power electronics can be as simple as a rectifier, or as complex as a microprocessor controlling multiple integrated circuits, which can switch from driving a motor to running a generator on the fly. They can control a motor's speed and torque output accurately, and provide voltage regulation for generators, among other functions.

Once we are able to drive a motor with one of our existing or breadboard drives, we will design a circuit board tailored to the motor and have it printed. We generally do all the required assembly in house or through our local partners.

McCleer Power can design and fabricate drives with working voltages ranging from automotive MOSFET based 13.5Vdc levels through utility/industrial IGBT or thyristor based medium voltage 4160Vac levels. Drives with power ratings of 100kW and below can be experimentally characterized in house.
