Features | 5-Phase Stepper Motor PKP/PK Series
Improved Performance
High Accuracy
Since the step angle of 5-phase PKP Series is at 0.72˚ (high-resolution type at 0.36˚) and the stopping accuracy is at ±0.05˚, highly accurate positioning is possible. In addition, the stop position accuracy controlled by a microstep driver has almost the same high accuracy as that controlled by a full-step driver.
Stopping Accuracy Does Not Get Worse With Microstep
(5-Phase CVD Series Driver + 5-Phase PKP Series Motor)
Low Vibration
As the 5-phase PKP Series has a small basic step angle of 0.72˚ (0.36˚ for high-resolution type), it is lower in vibration and noise than 2-phase stepper motors with a basic step angle of 1.8˚. Also, vibrations and noise can be further reduced through control with the driver of the microstep drive.

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.

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 |
---|---|
Resolution | 500 P/R, 1000 P/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 60 mm are also available with a resolution of 1000 P/R. Click here for details about products
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

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.
