Gear motor is a unit which creates mechanical energy from electrical energy and which transmits mechanical energy through the gearbox at a reduced speed. Gear motor consists basically of housing with inlet and outlet ports and a rotating group made up of two gears. An AC power gear motor consists of a series of three windings in the stator section with a simple rotating section and an integral gearbox or gear head. The changing field caused by 50 or 60 Hertz AC line voltage causes the rotor to rotate about the axis of the motor. AC motors are the most common and simple type of motor manufactured. A DC power gear motor consists of a rotor, a permanent magnetic field stator and an integral gearbox or gear head. The magnetic field is maintained using either permanent magnets or electromagnetic windings. DC motors are most commonly used in variable speed and torque applications.

Power generator is a transportable source of battery power. This fully integrated unit quietly generates DC or AC electricity to run small appliances such as lights, small televisions, fans, laptop computers and small power tools. It is designed to recharge from either a solar module or an optional AC battery charger. A controller monitors the charge to avoid under and overcharging the battery and a meter displays how much charge is in the battery. The AC model includes an internally mounted inverter that changes DC electricity to AC electricity for use with most appliances.
