Gear Motor

A gear motor is a combination of a gearbox and an electric motor. This combination of two systems is used for efficient usage of the motor. It makes a cost-effective solution for high torque, low-speed applications. These motors are used in our household as, garage door openers, alarm clocks. In commercial areas, hospital beds, cranes.
