Electric Motors

The RS range of electric motors has a variety of high quality solutions to suit your application. Featuring a wide range of motor types that are more adaptable and diverse than ever before, it is important to select the correct motor and peripherals to maximise the performance of your system.

Types of electric motors

Electric motors are used in motion control applications to convert electrical energy into mechanical energy. Typically DC electric motors are available in either brushed or brushless types. Brushless requires less maintenance as the brushes do not require replacement, and usually spin faster than brushed motors. The RS range includes the most commonly used types of electric motors.

• AC / DC Motors - Available in either brush and brushless types and synchronous and asynchronous
• AC / DC Geared Motors - Suitable where a specific RPM output is required
• Servo Motors - Allow for precise control of angular or linear position, velocity and acceleration
• Stepper Motors - Where motor speed is required to be in discrete steps

What accessories are available to use with electric motors?

In industrial automation processes, using accessory equipment for motors assists in operation and can also improve performance and increase efficiency. Some peripherals to consider are:

• Soft starts - reduce the torque and load during the startup phase to prolong lifespan.
• Motor starters - control the amount of electrical power during startup. They can also stop, reverse and offer protection.
• EMI filters - suppress electromagnetic interference which is generated by radio signals or through signal/power lines.
• Inverters (VFD Variable frequency drives) - a type of motor speed adjuster used in electro-mechanical drive systems. The drive controls the AC motor speed by changing the input frequency and voltage.
• Motor protectors protect motors against damage by monitoring motor health during operation.
• Stepper motor drivers control stepper motor speeds.
• Break modules stop motors in operation as an alternative to friction braking.
