AC electric motor gearbox

AC electric motor gearbox are a convenient and cost-effective choice for fixed or variable speed velocity control applications. These electric motor gearbox offer a range of winding options, including AC fixed speed, PSC or split-phase (single-phase) windings, and variable-speed AC three-phase inverter-duty windings, which are the most popular. They are widely used in a variety of industrial applications, such as conveyor systems, food processing equipment, medical equipment, and factory automation, due to their low maintenance, simple operation, and low cost.

AC motor gearbox are available in various styles, such as parallel shaft, planetary/inline, hollow shaft, and right-angle worm electric motor gearbox, with a rated power range from 1/25-3/4HP, gear ratios from 5:1 to 3600:1, and a rated torque of up to 1000 lb-in (113 Nm).

Greensky offers both Permanent Magnet DC (PMDC) and Brushless DC (EC) gearmotors that are designed to provide quick acceleration, deceleration, easy reversing, and high starting torque. PMDC gearmotors have a predictable performance as the output torque is directly proportional to the input current, while the electric motor gearbox output speed is directly proportional to the applied voltage. Additionally, PMDC gearbox are usually less expensive compared to inverter-duty AC geared motors and drives. The 12 and 24v DC motor gearbox are ideal for low-voltage applications, such as those driven by batteries or solar power supplies, and are commonly used in mobile, portable, and off-grid equipment.

Due to their high starting torque, PMDC electric motor gearbox are also frequently used in applications where the load is highest during start-up, such as conveyors and mixers. Greensky offers a range of PMDC electric motor gearbox, including parallel shaft, hollow shaft, right-angle, and Hypoid models, which are rated from 1/4 to 1/2 HP, with speeds ranging from 0.7 to 658 rpm and a rated torque of up to 1535 lb-in (173 Nm).

What is electric motor gearbox?

Electric Motor Gearbox, which are also known as geared motors or gear motors, are compact electric motors that come with an integrated gear reducer or gearhead that cannot be separated from the motor. These gearmotors work as speed reducers and torque multipliers, which reduces the motor power required to drive a particular load. The performance and lifespan of the gearmotor depend on various factors such as the gear housing design, gearing type, gear lubrication, and the mode of integration.

How to Select the Right electric motor gearbox?

When it comes to selecting the right electric motor gearbox for your application, there are several factors to consider. The gearbox is a critical component of an electric motor, and it plays a significant role in determining the motor’s performance and efficiency. In this article, we’ll discuss some of the key considerations when selecting an electric motor gearbox.

Understanding Gearbox Ratio

The gearbox ratio is one of the most important factors to consider when selecting an electric motor gearbox. The gearbox ratio is the ratio of the number of teeth on the input gear to the number of teeth on the output gear. A higher ratio means that the output shaft will rotate more slowly than the input shaft, but with more torque. A lower ratio means that the output shaft will rotate more quickly than the input shaft, but with less torque. The gearbox ratio can have a significant impact on the motor’s speed, torque, and efficiency.

Evaluating Gearbox Efficiency

Another important consideration when selecting an electric motor gearbox is the gearbox’s efficiency. The efficiency of a gearbox is the percentage of input power that is transferred to the output shaft. A more efficient gearbox will result in less power loss and higher overall system efficiency. Factors that can impact gearbox efficiency include gear material, lubrication, and manufacturing quality.

Selecting the Right Gearbox Type

There are several different types of electric motor gearboxes, each with its own advantages and disadvantages. Some of the most common types of gearboxes include spur gearboxes, helical gearboxes, worm gearboxes, and planetary gearboxes. Spur gearboxes are the simplest and most affordable option, but they can be noisy and less efficient than other types. Helical gearboxes are more expensive but offer smoother operation and higher efficiency. Worm gearboxes are compact and offer high gear reduction ratios, but they can be less efficient and generate more heat. Planetary gearboxes are the most complex and expensive option but offer the highest efficiency and torque density.


Selecting the right electric motor gearbox is critical to achieving the desired performance and efficiency in your application. When evaluating different gearboxes, it’s important to consider the gearbox ratio, efficiency, and type. By understanding these key factors and selecting the right gearbox for your application, you can ensure optimal motor performance and longevity.

The Ultimate Guide to Electric Motor Gearboxes

If you’re looking for a way to optimize the performance of your electric motor, a gearbox might be just what you need. Electric motor gearboxes are designed to increase torque while decreasing speed, making them ideal for a wide range of applications. In this guide, we’ll take a closer look at electric motor gearboxes, including what they are, how they work, and the benefits of using them.

What is an Electric Motor Gearbox?

An electric motor gearbox is a mechanical device that is used to increase the torque output of an electric motor. It does this by reducing the speed of the motor while increasing the amount of force that is produced. This is accomplished by using a series of gears that mesh together, allowing the motor to turn at a slower speed while still maintaining its torque output.

How Do Electric Motor Gearboxes Work?

Electric motor gearboxes work by transferring power from the electric motor to the output shaft. The gears in the gearbox are arranged in a specific way, with each gear having a different number of teeth. As the motor turns, it drives the first gear in the gearbox, which then turns the second gear, and so on. The final gear in the gearbox is attached to the output shaft, which then drives the load.

Benefits of Using an Electric Motor Gearbox

Using an electric motor gearbox can provide several benefits. One of the main benefits is increased torque. By reducing the speed of the motor, the gearbox allows it to produce more force, making it ideal for applications that require high levels of torque. Another benefit is increased efficiency. By reducing the speed of the motor, the gearbox reduces the amount of energy that is wasted as heat, resulting in a more efficient system overall.

Choosing the Right Electric Motor Gearbox

Choosing the right electric motor gearbox is crucial to ensuring that your system performs at its best. There are several factors to consider when selecting a gearbox, including the desired output torque, the speed range, and the load requirements. It’s also important to consider the type of motor that you’re using, as some gearboxes are better suited for certain types of motors.


Electric motor gearboxes are an essential component of many industrial and commercial applications. They provide increased torque and efficiency, allowing electric motors to perform better and last longer. When selecting a gearbox, it’s important to consider your specific needs and requirements, as well as the type of motor that you’re using. With the right gearbox, you can take your electric motor performance to the next level.
