Why the DC motors are mostly gear motors?

To reduce shaft speeds, many DC motors are paired with a gearbox. 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.

Is DC motor and gear motor same?

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. … A DC motor without gears is useful in many applications, for example the simple fan.

What are geared DC motors?

Geared DC motors can be defined as an extension of DC motor which already had its Insight details demystified here. A geared DC Motor has a gear assembly attached to the motor. … This concept where gears reduce the speed of the vehicle but increase its torque is known as gear reduction.

What is geared motor?

A gearmotor, also called a gear motor or a geared motor, is a combination of a gear system or gearbox and an electric motor. … Sometimes inaccurately called “gears motors,” or even geared motors, gearmotors generally combine an efficient motor, such as an Electrically Commutated Motor, with a gear reducer or gearhead.

What are the main advantage of gear motors?

Speed reduction: Gear motors are also known as gear reducers because as they increase output torque they decrease output speed. A motor running at 1,000 rpm fitted with a 5:1 ratio gearhead outputs 200 rpm. This speed reduction improves system performance because many motors do not operate efficiently at low rpm.

How do I choose a DC gear motor?

  1. Know your application requirements for your gearmotor. …
  2. Select the proper motor. …
  3. Know the speed and torque requirements of the load to be driven. …
  4. Test the motor Once you have selected a gearmotor, it is important to run several tests to ensure the motor runs well in a typical operating environment.


What is a standard DC motor?

A direct current (DC) motor is a type of electric machine that converts electrical energy into mechanical energy. DC motors take electrical power through direct current, and convert this energy into mechanical rotation. … The output torque and speed depends upon both the electrical input and the design of the motor.

Why geared motors are used?

A geared motor is a component whose mechanism adjusts the speed of the motor, leading them to operate at a certain speed. geared motor have the ability to deliver high torque at low speeds, as the gearhead functions as a torque multiplier and can allow small motors to generate higher speeds.

How does the DC motor works?

Electric motors turn electricity into motion by exploiting electromagnetic induction. The motor features a permanent horseshoe magnet (called the stator because it’s fixed in place) and an turning coil of wire called an armature (or rotor, because it rotates). …

How does a gear transmit power?

Gears are used for transmitting power from one part of a machine to another. … Similarly, in a car, gears transmit power from the crankshaft (the rotating axle that takes power from the engine) to the driveshaft running under the car that ultimately powers the wheels.

What are benefits of gears?

Advantages of Gear drive

  • It is positive drive hence velocity remains constant.
  • Provisions for changing velocity ratios can be made with the help of gear box.
  • Its efficiency is very high.
  • It can be used even for low speeds.
  • It can transmit high torque values.
  • It is compact in construction.


What is electric motor drive?

The term “electric motor drive” applies to all drives driven by electric motors. Several types of electric motors, supplied with direct or alternating current, serve the purpose. … The main parameters of an electric motor drive are power, torque, and rate of revolution or the number of revolutions per unit of time.
