Gear motors use either AC (Alternating Current) or DC (Direct Current) power. In most cases, the gear reducer is intended to multiply the available output torque without increasing the power consumption of the motor while maintaining a compact size.
What is an electric gear motor?
A gearmotor (or geared motor) is a small electric motor (AC induction, permanent magnet DC, or brushless DC) designed with an integral (non-separable) gear reducer (gearhead) attached. ... In general, gearmotors function as torque multipliers and speed reducers, requiring less motor power to drive a given load.Aug 6, 2019
What is a gear reduction motor?
A gear reducer is a mechanical transmission device that connects a motor to a driven load. It is also known as a gearbox. It allows you to modify the torque and speed between a motor and a load. Reduction gear assemblies are made up of series of gears.
How does a gear motor work?
Essentially, a gearmotor is a pairing of gear reducer and ac or dc electrical motor. The gear and the motors are combined into one unit. A gearmotor delivers high torque at low horsepower or low speed. ... These motors use gears, typically assembled as a gearbox, to reduce speed, which makes more torque available.May 7, 2015
What is AC geared motor?
Gearmotors (also called geared motors or gear motors) are small electric motors designed with an integral (non-separable) gear reducer (or “gearhead”) attached to the AC, PMDC or BLDC motor. Gearmotors function as torque multipliers and speed reducers, requiring less motor power to drive a given load.
What is AC motor and how it works?
An AC motor is an electric motor that uses alternating current to produce mechanical energy using magnetism blended with alternating current. The structure of an AC motor includes coils that produce a rotating magnetic field inside a rotor attached to an output shaft, which produces a second magnetic field.
What is AC motor example?
Induction motors, linear motors, and synchronous motors, for example, are all types of AC motors. AC motors can also include variable-frequency drives to control the motor's speed and torque, while DC motors are available in self-excited and separately excited-type models.
Where are Bodine motors made?
Bodine is headquartered in Northfield, Illinois with our main manufacturing plant in Peosta, Iowa.
Who owns Bodine?
David J. Rathje purchased the company from Cast in 1965, and Bodine continues to be locally owned and operated today. In 1993, David W. Rathje became the current president.
What is the use of geared DC motor?
Gears Harness the Power of DC Motors This helps to reduce the motor's shaft speed, and increase the torque output of the motor. In most cases, torque is increased by the ratio of the gear reduction, minus any losses in the gearbox.
What is the difference between DC motor and DC geared motor?
1 Answer. A DC motor is not the same as a "gear motor" - a "gear motor" may be an AC or DC motor coupled with a gearbox or transmission. A gear motor adds mechanical gears to alter the speed/torque of the motor for an application. Usually such an addition is to reduce speed and increase torque.
Why are DC motors more efficient?
They run faster than induction motors due to the fact that the speed is reduced by the slip of the asynchronous motor. ... In fact, the DC motor is 30% more efficient than AC motors due to the secondary magnetic field being generated from the permanent magnets rather than copper windings.Aug 24, 2017
