ISL Products offers compact and economical DC Spur Gear Motors to meet your application needs. We can design and manufacture both the DC motor and spur gearhead together for the best solution. These motors are cost-effective and reliable for applications with lower torque and speed requirements. With a range of reduction ratios, precision-cut gears, voltages, and sizes available, ISL Products has a spur gear motor suited to meet your application requirements.

An ISL spur gearmotor features one of our, many types of, dc motors coupled with one of our unique spur gearheads. The internal construction of our spur gearhead consists of straight-toothed, inter-meshed gears that control the torque and speed output of the gear motor. The gear train consists of large and small gears mounted on parallel shafts that are offset from each other. As the smaller gears mesh with the larger gears, it reduces and transforms speed into torque. The gear train arrangement of a spur gearhead is designed to hold all of the load on a single point of contact between the two gears; adding more gears lowers output speed and increases output torque.

More about Spur Gear Motors

A Spur Gear Motor from ISL Products features one of our various types of direct current motors coupled with one of our robust gear heads. When you couple a DC motor with a spur gearbox, a speed reduction will occur, creating more torque output at the output shaft. A Spur gear system consists of several straight-cut or helical-cut gears that mesh against each other to increase continuous torque at the output motor shaft.

Spur gear motors are much simpler than their counterpart, planetary gear motors. In a spur gear electric motor, the gearing is different in that each gear only has one contact point with the next gear. To increase the gear ratio more stacks of gears are added together. Learn more about spur gear motors vs. planetary gear motors by reading our intuitive design note.

Our wide range of spur dc gear motors offer economical options for your applications, no mater the gear reduction ratio. Our internal gear spur motors are available in both permanent magnet brush motors and brushless motor options. They typically range in diameter from 40mm down to micro dc gear motors of 10mm. We also manufacture pear shaped spur gear motors for applications with space constraints.

ISL Products has been a top gear motor manufacturer for decades. If you need a more custom solution just let us know because our capabilities are endless. Standard options are available and in stock as well.

Spur Gear Motors FAQ's

What is a spur gear motor?

A spur gear motor is a type of gear motor that uses spur gears, which are the most common type of gear used in transmission systems. Spur gears have straight teeth that are parallel to the gear axis, giving them the ability to transmit motion and power efficiently. Spur gear motors are often used in applications where high torque and precision are required, such as in robotics, industrial machinery, and automotive systems. They are known for their simplicity, reliability, and compact size.

Why do spur gear make noise?

Spur gears can make noise due to a few reasons. One common reason is improper alignment of the gears, which can cause them to not mesh correctly and produce a loud noise. Another reason could be worn or damaged gear teeth, leading to a rough and noisy operation. Additionally, lack of lubrication between the gears, on the tooth surfaces, can cause increased friction and noise. Regular maintenance and proper alignment of spur gears can help reduce noise levels.

What is the principle of spur gear?

The principle of a spur gear is based on the transfer of motion and power between two mating gears with straight teeth. When the teeth of two spur gears mesh, they rotate in opposite directions. The principle of operation involves the teeth of the gears interlocking and transferring rotational motion from one gear to the other. Spur gears are commonly used in mechanical systems to transfer power from one shaft to another efficiently and smoothly. This can be done either internally inside a gearbox or with external gears.

What is the difference between a planetary gear motor and a spur gear motor?

A planetary gear motor consists of multiple gears (planet gears) that rotate around a central gear (sun gear) within an outer ring gear (annulus). This design allows for high torque output and compact size, making it ideal for applications where space is limited. On the other hand, a spur gear motor consists of two gears that mesh together, with the teeth of the gears being aligned parallel to the axis of rotation. Spur gear motors are simple in design and more efficient than planetary gear motors at high speeds. However, they may not be able to handle as much torque as planetary gear motors. In summary, the main difference between a planetary gear motor and a spur gear motor is their design and performance characteristics, with planetary gear motors offering higher torque output and compact size, while spur gear motors are simpler and more efficient at high motor speeds.
