RS Pro 42mm Planetary Geared Motor - 975D Series

From RS Pro, this planetary geared DC motor is made from premium materials, and boasts a high quality construction. As such, it is suitable for use in heavy duty environments.

This DC geared motor uses a brush to deliver current to the motor windings. As such they ensure a a low cost and simplified design, while still offering versatility and reliability. They are ideal for low speed applications that require high starting torque.

The gear motor features a planetary gearhead, with bronze output bearings that guarantees a high torque transfer from the motor through the gearbox.

This 42 mm geared motor is designed for most low voltage applications, and provides a 55 rpm no-load output speed.

Features and Benefits

• 12 V dc Supply Voltage
• Robust units which boast a high quality motor
• Sintered bronze bearings
• High Efficiency

Applications

DC geared motors are highly versatile, and are used in many appliances and technologies. Whether you're a hobbyist or industrial manufacturer, this DC electric motor can be used in both model and industrial applications. Typical applications include;

• Prototyping
• Water pumps
• Camera Systems
• Robotics
• Fans

What are the Advantages of a Planetary Gearhead?

A planetary, or elliptical, gear system can bring many advantages to a DC motor. As well as allowing the motor to multiply torque, if can also offer speed reduction to improve system performance and efficiency. Gear heads can also reduce the effects of overshoot by ensuring the motor inertia better matches the load inertia.

What's the Difference Between Brushed and Brushless DC Motors?

Electric motors that use a brush to deliver current to the motor windings have a simpler construction than their brushless equivalents, and are therefore usually lower in cost. They are also able to be wired directly to a DC power source, and have no need for an encoder or drive, which results in more simplified wiring options.

Unfortunately, wear and tear on the brush element means a shorter service life and less efficiency. They are also typically noisier than brushless DC motors.
