DC Brush Motorselection
Rotary
ERIKS represents several DC-motor suppliers. All motors have their unique characteristics and properties.
We speak about DC motors if they can be supplied with a DC power supply or battery. In the literature you also find the term PM motors. PM means: Permanent Magnet. You also will recognize DC motors by their use of brushes. Some can be exchanged from the outside others can not be exchanged. DC motors are generally used for low and medium dynamic continous operations. The life span of DC motors is determined by the wear of the brushes. The wear is hard to predict, but it is caused by a combination of speed and current. The average life span of a DC motor is about 3000 hours. This will be more as soon as the speed and current are below the nominal specifications. For example: a oversized motor will last longer.
All controllers mentioned below can be programmed. The DIMC241, IIF32 and IMC2410 are designed for small and medium series of customized applications, which will be programmed in machine code. Usually this is done by ERIKS.

Linear actuators - single units
Linear actuators can be used in various ways. For example as an alternative of air of hydraulic systems. It is cleaner and more controllable than pneumatic or hydraulic systems. Also are they excellent in combination with battery powered systems, such is used in the car industry.
Typical applications:
- agriculture applications in and around farm houses
- agriculture machines such as spraying machines
- valve adjustment
- belt tensioning
- table adjustment
- scanning systems
- production machines
- movements underneath robots
- lifting devices
- etc.

DC-motor - brush - built-on/CANopen
ERIKS has developed compact DC motor units which consists out of standard DC motors with encoder, 4Q amplifier and motion controller, including CANopen. The assembly is mounted in a solid housing. They are available in 2 sizes, namely the RC30 and the RC63.
CANopen
The CANopen protocol is a communication protocol that communicates at the Controller Area Network (CAN). CAN is an industrial network and it is well known for its high flexible configuration capabilities. CAN is also known for its high reliability rate and it is insensible for interference. This is reached by using 5 levels of detecting and signaling errors.
Characteristics
- CANopen servo for direct connection to the CAN fieldbus.
- PM-DC-Motor, 4Q servo-amplifier and built-in closed-loop positioning control are integrated into one single device.
- Numerous forms are available due to the flexible construction by changing mechanical properties, like speed, stroke, force, built in length, etc. *
- the RC30 unit with the PLG32 gearbox can be used in combination with the PLG H33. This is a right angular gearbox with a ratio of 1:1. For further information see the datasheet of the PLG H33 (176kB)
- optional: 2x bi-directional input/outputs, for example limit switches (NPN/PNP 100mA).*
* only for RC63
| Specifications | RC30 | RC63 |
|---|---|---|
| Max. torque | 3 Nm | 23 Nm |
| Max. Velocity | 3000 rpm | 3000 rpm |
| Supply voltage | 15..40 VDC | 24 VDC |
| Protection class | IP40 | IP52 optional IP65 |
