Why geared motor is used?
Electric Gear motors are used in applications that require high output torque and lower output shaft rotational speed, especially where space and available power are limited. This describes a wide range of common equipment applications across multiple industries.

What are the main advantages of gear motors?
10 Advantages of Geared Motors
- High Torque Output.
- Speed Reduction.
- High Resolution.
- Drive Large Inertial Loads.
- Shorter Positioning Time.
- Downsize.
- Improved Damping Characteristics.
- Increased Axial and Radial Load.
How does a DC geared motor work?
What is a DC Gear Motor? A gear motor is an all-in-one combination of a motor and gearbox. The addition of a gear head to a motor reduces the speed while increasing the torque output. Most of our DC motors can be complemented with one of our unique gearheads, providing you with a highly efficient gear motor solution.
How does gear increase engine torque?
The rotary machine’s output torque is increased by multiplying the torque by the gear ratio, less some efficiency losses. While in many applications gear reduction reduces speed and increases torque, in other applications gear reduction is used to increase speed and reduce torque.
What is motor driver?
A motor driver is a small Current Amplifier whose function is to take a low-current control signal and then turn it into a higher-current signal that can drive a motor. The L293D is a typical Motor Driver which can drive 2 DC motors simultaneously.
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.
Why are gears used with DC motors?
Gears Harness the Power of DC Motors These shaft speeds exceed the acceptable range for many applications, in most cases by a wide margin. 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.
What are DC motors used for?
Small DC motors are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight brushed motor used for portable power tools and appliances. Larger DC motors are currently used in propulsion of electric vehicles, elevator and hoists, and in drives for steel rolling mills.
Why are DC motors used?
DC motors offer highly controllable speed. By changing the armature or field voltage it’s possible to achieve wide speed variation and with this level of controllability, DC motors offer the precision required by a wide range of industry applications.
What is torque and why is it important?
Torque is a crucial part of generating power from a car’s engine, as it represents the load an engine can handle to generate a certain amount of power to rotate the engine on its axis. The force is measured in pounds (lb) per foot (ft) of rotation around one point.
What should the RPM be for a fractional horsepower motor?
Typical no load or synchronous speeds for an AC fractional horsepower motor are 1800 or 3600 rpm, and 1000-5000 rpm for DC fractional hp motors. If an application calls for a slower speed and/or higher torque, then a gear motor should be considered. To learn more about adding a reducer, check out Part 2,…
What is the RPM of a 4 pole motor?
So, for example, if you have a 4 pole motor on 60 Hz then RPM=60* (2/4)*60=1800 rpm.
What is the nameplate speed of an electric motor?
If an electric motor has a nameplate speed of 1,800 rpm, one can conclude that the unit is a 4-pole synchronous motor rated for 60 Hz. On the other hand, if the nameplate speed has a lower value like 1,760 rpm, the unit is an induction motor.
What are some industrial uses for a motor?
Conventional industrial uses include blowers, machine and power tools, fans and pumps. Hobbyists generally use motors in smaller applications requiring movement such as robotics or modules with wheels.
