A gearmotor is an all-in-one combination of an electric motor and a gearbox. This makes it a simple, cost-effective solution for high-torque, low-speed applications because it combines a motor with a gear reducer system.
What is meant by gear motor?
Definition of gearmotor : an electric motor with various output speeds secured by attached combinations of gears.
What type of motor is a gear motor?
What Are Gear Motors? Simply put, a gear motor is an electric motor coupled with a gearbox. In most cases, the addition of a gearbox is intended to limit the speed of the motor’s shaft and increase the motor’s output torque.
What is the function of gear motor?
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.
What is the difference between motor and gear 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.
What are the advantages of gear motor?
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.
Why do we use gearbox in motor?
A gearbox—otherwise known as a gear reducer or speed reducer—is a set of gears that can be added to a motor to drastically decrease speed and/or increase torque. Each gearbox type works in unison with a motor to achieve the desired speed-torque output.
What is a gear motor Wikipedia?
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. The most important parameters in regards to gear motors are speed (rpm), torque (lb-in) and efficiency (%).

How do I choose a gearbox motor?
Basics of Gearbox Selection Service Factor. Before sizing an application, the customer should determine the service factor. Ambient Temperature and Environment. Shock Load or Type of Load. Output Style or Mechanism. Output Shaft or Hollow Bore Size. Housing Styles.
What are the types of motor?
The types of Electric motors are available in three main segments like AC motor, DC motor, & special purpose motors. types-of-motors. dc-motor. ac-motor. special-purpose-electric-motor.
Does gearing down a motor increase torque?
Gearing down reduces the speed at the rear wheel with a corresponding increase in torque. This does not affect the power of the engine apart from frictional losses.
Do motors have gears?
While internal combustion engines require multiple gears with different ratios for power output, electric motors produce a consistent amount of torque at any given RPM within a specific range. Additionally, most electric motors can operate beyond 10,000RPM with ease.
What is difference between Bo motor and DC motor?
BO motors have lower speeds than the normal DC motors because of the gearing present inside the assembly. Although, both might be using the same motor, due to the gear sets, the torque developed is much higher in a BO motor when compared to the normal DC motors.
Why are gearboxes needed?
The purpose of a gearbox is to increase or reduce speed. As a result, torque output will be the inverse of the speed function. If the enclosed drive is a speed reducer (speed output is less than speed input), the torque output will increase; if the drive increases speed, the torque output will decrease.
How does gear increase engine torque?
Small drive gear, large driven gear. Speed will decrease, torque will increase. As a quick-and-dirty example – you have a 20-tooth drive gear (input) and a 60-tooth driven gear (output.) Your gear ratio will be 3:1, so your input speed will be divided by three, and your input torque will be multiplied by three.
How does the gearbox work?
Most modern gearboxes are used to increase torque while reducing the speed of a prime mover output shaft (e.g. a motor crankshaft). This means that the output shaft of a gearbox rotates at a slower rate than the input shaft, and this reduction in speed produces a mechanical advantage, increasing torque.
Does gear increase speed?
Gears serve two main purposes: increasing speed or increasing force. In order to increase one of these, compromises must me made. For example, to increase the speed of a bicycle’s wheels the force applied to the pedals must be increased. Similarly, to increase the force on the wheels the pedals must be turned faster.
Why are DC motors used?
DC motors have the advantage of: higher starting torque, quick starting and stopping, reversing, variable speeds with voltage input and they are easier and cheaper to control than AC. While the market for AC motors is larger than DC, it can be challenging to find AC solutions with fractional horsepower ratings.
What makes a motor move?
How do motors work? Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current.
What are the 4 types of gears?
Read on to learn the different types of gear and the applications and industries that utilize them. Spur Gear. Spur gears transmit power through shafts that are parallel. Helical Gear. Double Helical Gear. Herringbone Gear. Bevel Gear. Worm Gear. Hypoid Gear.
