1.8° motor and driver packages providing high torque in the low-speed range. With China Motor’s new winding design and high-efficiency driver circuit design, the performance has been brought to their full potential, resulting in significant increases, especially in torque at lower speed ranges. In particular, torque in the 250 r/min range has been increased by 50% compared to conventional products allowing for quicker moves. Vibration and noise have been greatly reduced compared to conventional 1.8° stepper motor performance.
0.72° and 0.36° motor and driver packages have higher torque in the upper speed ranges. With China Motor’s advanced technology and microstepping performance, even improved positional accuracy, lower vibration and noise can be achieved easily. Torque in the 500 r/min range has increased up to 85% compared to conventional products. In addition, the fully digital-controlled microstep driver has further improved the low vibration and noise reduction factors.
Characteristics
Torque
By adopting a higher current motor winding specification, the usage range is now much wider.
Vibration
Lower vibration and further noise reductions have been achieved through the use of a fully digital-controlled microstep driver.
Motor technology in comparison
It can be summarized, that the maximum holding torque in the low-speed range is achieved with the 1.8° 2-phase stepper motors and driver packages through the use of a high motor current design and specification. The speed range has increased considerably with the 0.72°and 0.36° 5-phase motor in comparison to the 1.8° motor.

Provides high torque in the higher speed range.
Low Vibration with Full-Time Microstepping
Low vibration and noise reduction have been achieved across all speed ranges by significantly improving the vibration level with the use of a fully digitalcontrolled full-time microstep driver. The 0.72° and 0.36° 5-phase CVK Series has further improved vibration characteristic.
Vibration Characteristics of a
conventional stepper motor
CVK Series Vibration characteristics for 0.72°/0.36° stepper motors have been significantly improved.
Reduced Vibration
The new smooth drive control with advanced current control increases the basic step angle to a maximum resolution of 2048. As a result, a reduction in step vibration in the lowspeed range is achieved.
Vibration Suppression Control
Common vibration that occurs in the mid-speed range has been suppressed. This enables more stable torque characteristics.
For High accuracy demands it is recommended to use a 0.72°/0.36° Stepper Motor
In general, stopping accuracy tends to be lower during microstep operation* than full step operation and this effect is more noticeable in a 1.8° motor. In this situation, using a CVK Series 0.72°/0.36° stepper motor enables a higher positioning accuracy.
