Geared Motor Types and Their Importance

A geared motor is a component designed to adjust motor speed while delivering higher torque at lower speeds. The gearhead works as a torque multiplier, allowing a relatively small motor to produce the required output torque efficiently. Understanding the types of geared motors is important because different gear configurations are designed for specific operating conditions, speed requirements, and torque applications.

A geared motor can also be described as a gear reducer because it combines a motor with a speed-reduction mechanism, typically functioning as a gearbox. By reducing the motor’s output speed, it makes higher torque available for applications that require controlled and consistent power transmission. This is why understanding geared motor types and their Importance can help in selecting the right configuration for a particular industrial application.

Based on the type of motor and gear mechanism they use, geared motor types include bevel, helical, hypoid, spur, and worm geared motors. Each type has its own advantages and limitations depending on factors such as torque capacity, speed reduction, efficiency, noise, and operating conditions.

For example, helical gears generally offer higher torque capacity and smoother, quieter operation than spur gears. Worm gears, on the other hand, are commonly used where high speed reduction and controlled output speed are required. Understanding these differences is essential when choosing from the various types of geared motors for a specific application.

Geared motors can be classified based on different elements. The two most common geared motor types are right angle geared motor and inline geared motor.

• Right-angle geared motor use worm, bevel or hypoid gearing.
• Inline geared motor typically use spur gears, helical or planetary gear sets.
• Parallel shaft geared motors type helical gears

The helical gear units are coaxial units where the gear unit output shaft is in-line with the motor shaft. The in-line helical motors are mostly used for slow speed/high torque applications.

This type of geared motor which uses gears to accomplish speed reduction. The motor shaft and the speed reducer shaft are on parallel planes in this specific geared motor.

• Agitator, Conveyors, Carriage Drives & various material handling equipment.
• Industries– Sugar, Paper, Cement, Pharmaceuticals, Food processing

This is one of the simplest types of geared motor composed of a toothed worm wheel, generally made of bronze with a steel shaft at its centre. The wheel is constantly in contact with the steel screw whose shape looks like that of a worm.

The shafts are set up at a 90-degree angle which is one of its main features.

These types of geared motors are angular geared motors with the output shaft rotated through 90 degrees to the motor shaft. For high output torques, helical geared motor is desirable, as there is a requirement of high density of power of angular geared motor.

• Packaging, Mixing, Conveyor, Cranes
• Industries- Food Processing, Paper, Sugar, Cement, Material Handling, Pharmaceuticals

• Analyse and correct the mechanical noise levels by subjecting them to tests using frequency measurement equipment.
• The optimal torque measurement of starting torque, output torque and rated torque ensures proper transmission of the motion of the machine.
• Energy efficiency is an important factor to bear in mind, as the disposition of the gear train, the characteristics of rolling bearings enhance the performance across the entire system.
• Tests need to be carried out to measure the resistance, limits and the speed reducer service life. Premium Transmission provides expertise in testing technologies which guarantees the delivery of quality geared motor.
