Features | 2-Phase Stepper Motor PKP/PK Series
Improved Performance
Higher Torque
Higher current is now possible due to a review of the motor winding design. Increased torque over the entire speed range from low to high is achieved.
Comparison of Speed - Torque Characteristics of the Same Size Motors
Comparison of Maximum Holding Torque
Energy and Power Saving
By reducing the operating current supplied to the motor, the same torque as conventional products can be obtained while reducing power consumption and CO2 emissions.
Power consumption and CO2 emissions are reduced by 56 % compared to the conventional products(compared to our products)
Rotation Speed | 0.1 kHz (30 r/min) |
---|---|
Operating Time | 24 hours a day, 365 days a year |
Operating Conditions | 50 % in operation, 50 % on standby |
Power Supply Voltage | 24 VDC |
CO2 Coefficient | 0.519 kg-CO2/kWh |
Low vibration
Revising the magnetic design has achieved lower vibration than with conventional products.
Save Resources Through Downsizing
Torque improved considerably compared to conventional products. When compared at equivalent torque, using the PKP Series enables motor downsizing. This helps to save space and reduce the weight of the equipment.
44 % reduction in volume when comparing dimensions!

Compact and Flat Connector
The PKP Series uses a compact and flat connector, which lowers the connector's overhang (excluding some products). In addition, flexibility for the motor cable outlet direction has been increased, as outlet direction points upward.
- *For details, refer to the dimensions diagram of each motor.
With Encoder
Models equipped with an encoder are available. Comparing the command position and current position enables you to check the normal operation of the motor.
Encoder’s Main Specifications
Type | Standard Type | High-Resolution Type SH Geared Type |
---|---|---|
Resolution | 200 P/R, 400 P/R 1000 P/R* |
400P/R |
Angular Accuracy | ±0.36° (converted value at motor output shaft) | |
Output Signals | Phase A, Phase B, Phase Z (3ch) |
- *The standard types with a frame size of 42 mm and 56.4 mm are also available with a resolution of 1000 P/R.
Angle Accuracy
This is the calculation error between the actual rotation angle and the angle output from the encoder.
Motor Position Detection is Possible
Monitoring the current position and detecting positional errors are possible.
For example, comparing the command position and current position enables you to check the normal operation of the motor.
System Configuration Example
- *Converted value at motor output shaft
Enables Highly Repeatable Return-to-Home Functioning
Since the Z-phase signal is output at the step "0" position (stability point), it can be a substitute for the home sensor (a sensor attached to the motor shaft that detects the home within one revolution).
It also makes it easier to use the Z-phase output signal and TIM output signal* together and improves the repeatability of the return-to-home function.
- *This is the signal output from the driver each time the motor output shaft rotates 7.2° (3.6° for high-resolution types) from the home position.
When the Timing of Z-phase Output is Fixed
New Encoder (Magnetic type)
It outputs Z-phase signals with a width of ±3.6° centered on the step "0" position (stability point).
When the Timing of Z-phase Output is not Fixed
Since the output timing of the Z-phase signal is not fixed, it is difficult to use it as a substitute for the home sensor, and it is also difficult to use it together with the TIM signal.
Compact Encoder Equipped
When the frame size is 56.4 mm

Choose Between Voltage Output Type and Line Driver Output Type
A voltage output type and line driver output type are available.
A useful cable for wiring the encoder is also available separately.
