The RK Series incorporates new functions and state-of-the-art technologies to achieve the ultimate utility of a control motor. The series offers various types including the standard type, IP65 rated motor type and three geared types. Three frame sizes of 1.65 in. (42 mm), 2.36 in. (60 mm) and 3.35 in. (85 mm) [3.54in. (90 mm)] are available. The wide-ranging motor variations and affordable price make the RK Series a perfect solution for your various applications.
Smooth Drive Function
The Smooth Drive Function ensures low-vibration and low-noise operation at low speeds by internally executing microstepping within the driver, working independently of the input pulse frequency of your controller.
Microstep Drive System
The motor's basic step angle is divided by a maximum of 1/250 without the use of a reduction mechanism or other mechanical means. 16 resolution levels are available to set the desired resolution. This enables fine positioning and the further reduction of vibration and noise. A motion sequence of "low-speed transfer > high-speed return" can easily be performed without the need for changing from a microstep pulse frequency to a full-step operation. The RK Series can also be used in full-step operation.
100-115 VAC, 200-230 VAC Power Source Variation
The RK Series can be used with most common power supplies available around the world. They also comply with the international standards, ensuring safe operation.
Improved Angle Accuracy
Angle accuracy may decrease during use of microstep drivers, due to the effect of current control. However, the drivers used in the RK Series are designed to ensure that the motor operates at maximum accuracy.
Improved Response
The RK Series, with its high starting frequency, shortens the machine cycle without affecting acceleration/deceleration rates. This produces a significant savings in time for an operation in which the same cycle is repeated thousands of times each day.
Compliance with Safety Standards
The RK Series complies with the UL/CSA and EN standards. (With the RK54* type, only the driver conforms to the CSA standard.) The CE marking certifies compliance with the EMC Directive and Low-Voltage Directive. Additionally, the RK Series conforms to the EMC Directive only through its use of surge arrester. The RK Series doesn't require an external ferrite core or filter in the motor line or power line.
A Full Lineup Including Geared and IP65 Rated Type Motors
The geared types enable driving of large inertial loads and positioning at higher accuracy, while the IP65 rated motor provides ingress protection against dust and water. The RK Series offers a wide range of models meeting the needs of various applications.
RoHS Compliant Models Available
RoHS (Restriction of Hazardous Substances) Directive:
Directive on restriction of the use of certain hazardous substances in electrical and electronic equipment (2002/95/EC).
The RoHS Directive prohibits the use of six chemical substances in electrical and electronic products sold in the EU member states. The six controlled substances are: lead, hexavalent chromium, cadmium, mercury and two specific brominated flame-retardants (PBB and PBDE).
