Gear motors are vital components in numerous drive systems. Their versatility, stemming from various designs and configurations, allows them to amplify torque, decrease speed, reverse direction, or modify the push or pull exerted by a driveshaft. For over eight decades, Sumitomo Drive Technologies has been at the forefront, delivering top-tier gear motors, gearboxes, and speed reducers that incorporate industry-leading technology and fully integrated, premium-efficient motors. These robust power transmission units are available in diverse shaft configurations, including right-angle, concentric, and parallel shaft designs.

Understanding Gear Motors
Gear motors are more than just motors; they are integrated systems designed to provide specific speed and torque outputs. The combination of a motor and a gearbox allows for precise control and efficient power transmission, making them ideal for a wide range of applications.
What is a Gear Motor?
A gear motor consists of a motor, gears, and bearings, all enclosed within a housing. These devices are commonly employed in scenarios demanding substantial force (torque) at lower speeds. AC-powered gear motors excel in high-power applications such as lifting, jacking, and robotics. Accessories like brackets, covers, and extension cables facilitate mounting, protection, and power supply.
How Do Gear Motors Work?
The gear unit, with its internal stages, is the heart of a gear motor’s operation. It efficiently transfers the motor’s force from input to output, effectively converting speed and torque.
Fundamentally, gear motors are speed controllers. They typically reduce motor rotational speeds while simultaneously increasing torque output, exceeding what an electric motor can achieve alone. The design of the gear motor dictates its suitability for light, medium, or heavy loads, as well as the duration it can sustain power.
Reduction ratios, or gear ratios, indicate the extent to which the device reduces or increases the motor’s input speed. Another critical performance indicator is the maximum output torque, measured in Newton meters (Nm), representing the force the gear motor can exert and the load it can move.
Types of Gear Motors
The primary classification of gear motors hinges on the shaft configuration of the gear unit. The common types include:
- Right-Angle Gearmotors: Offer a 90-degree change in direction, ideal for space-saving applications.
- Parallel-Shaft Gearmotors: Input and output shafts are parallel, providing efficient power transmission.
- Concentric Gearmotors: Input and output shafts are aligned, offering a compact design.

AC vs. DC Gear Motors
Choosing between AC and DC gear motors depends on the specific requirements of the application. Here’s a comparison:
- DC Gear Motors: Ideal for applications demanding precise speed control or frequent starts and stops. Advantages include high torque and power output, precise speed control, good starting and stopping capabilities, and compact design. Disadvantages include higher costs and more complex control systems.
- AC Gear Motors: Suited for applications requiring constant speed, such as conveyor systems, pumps, and compressors. Advantages include high reliability, low maintenance, smooth operation, and energy efficiency. Disadvantages include limited speed control and potential overheating at high loads.
Factors to Consider When Selecting a Gear Motor
Selecting the right gear motor involves considering several critical factors:
- Load Requirements: Understanding the torque and horsepower needed for the application.
- Duty Cycle: Assessing the operating hours per day and the frequency of starts and stops.
- Speed Requirements: Determining the desired output speed for the application.
- Environmental Conditions: Considering factors like temperature, humidity, and exposure to corrosive substances.
- Mounting Position: Choosing the appropriate mounting orientation for the gear motor.
