The CRK Series with a built-in controller and self correction function features a 0.36° or 0.72° stepping motor offering the lowest vibration, increased positional accuracy and highest resolution, with 5 frame sizes, 5 different geared types and encoder options available. Each unit features a compact, space saving stepping motor and microstepping driver with a powerful, feature-rich controller built in. Frame sizes of 0.79 in. (20 mm), 1.10 in. (28mm), 1.18 in. (30mm), 1.65 in. (42 mm) and 2.36 in. (60 mm) are available. Encoder options available on the 1.65 in. (42 mm) and 2.36 in. (60 mm) with a 3 channel, 500 or 1,000 line encoder option based on motor resolution. The driver supports stand alone or RS-485 communications with multi-drop capability for network operation and I/O control.
- Lower Vibration
- Increased Position Accuracy
- Higher Resolution
NEW! Self Correcting Function
When Self Correcting Function is enabled and synchronism is lost, the controller makes sure that the motion profile is completed correctly. Total distance remains the same.
*Self Correcting Function requires encoder motor to provide feedback to controller.
Motor Types
High-Resolution Type Motors
The positioning accuracy of a stepping motor is affected by the friction of the load.
The high-resolution motor type achieves high accuracy and reliability based on Oriental Motor's latest precision machining technology. The motor resolution is increased to double the level of a standard model to reduce the displacement angle against load torque, thereby acheiving high positioning accuracy. Vibration is also reduced.
The high-resolution type is designed with a stop position accuracy of 2 arc minutes (0.034°) [standard type: 3 arc minutes (0.05°)]. The reduced error helps improve the positioning accuracy of your equipment.
High-Torque Type Motors
The high-resolution type and high-torque type adopt a newly designed high-torque motor that widens the range of applications.
- The smaller motor allows for compact equipment design.
- The motor current is reduced to suppress heat generation.
Example: Avoidance of temperature rise in precision equipment or machinery.
