- RK Series Stepping Motor & Driver Packages The RK Series incorporates new functions and state-of-the-art technologies to achieve the ultimate performance of a stepping motor. The series offers various types of motors including the standard type, IP65 rated motor type, Harmonic, Planetary and Taper Hobbed geared stepping motors. 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-range of 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. Sixteen resolution levels are available, enabling fine positioning and 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 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. Protective Earth Terminal [Excluding motors with a frame size of 1.65 in. (42mm)] Extended Bearing Life The life of a motor is affected by its bearing. The RK Series achieves approximately twice the life of a conventional motor by adopting a modified bearing. [Available only with the standard type with a frame size of 2.36 in. (60mm) or 3.35 in. (85mm).] Encoder Option Available
The RK Series stepping motor with encoder offers high torque and precise feedback capability.
