Features | Stepper Motors PKP Series/CVD Series Pulse Input Driver

Low vibration, high torque, and high efficiency features are introduced here.

Low Vibration

Full-time microstep drive with full digital control has greatly improved the vibration level, resulting in lower vibration in all speed ranges.

Significantly Improved Vibration Characteristics in All Speed Ranges

5-Phase Motor for Even Lower Vibration

Higher Torque

High torque is achieved by combining a high-current driver and a motor with an optimized winding design.

• PKP Series Motor: Higher torque due to revised winding design
• CVD Series Driver: High current drive is possible due to higher efficiency of the drive circuit

2-Phase Motor Increased Torque in Low Speed Range

5-Phase Motor Increased Torque in All Speed Ranges

High Efficiency Design

The CVD Series achieves higher torque by increasing the output current compared to conventional products. The design takes into consideration the reduction of heat generation so that the output current can be increased.

The torque of 2-phase stepper motors in the low speed range and 5-phase stepper motors primarily in the high speed range has been greatly increased. You can select a motor suited to your specifications from a wide range of speeds and torques.

Application: Inching operation over short distances.

For applications that require rapid acceleration and deceleration, a 2-phase stepper motor with high-torque at low speed is recommended.

Application: Long distance back-and-forth operation.

For applications that require high-speed range, a 5-phase stepper motor with high-speed torque is recommended.

Application: Inching operation over short distances with large amount of inertia.

For applications that require acceleration and deceleration with higher torque, geared types are recommended.
