Issue: To Space Saving by Reducing External Encoders
Conventional Problems
- There is a need to develop a new, smaller model of medical inspection equipment
- External encoders are installed for position control of each drive shaft, so it is necessary to reserve space for these encoders
- Man-hours required to assemble and inspect external encoders, as well as parts management work time
Solution: Stepper Motor With Encoder Achieves Space Saving
Space saving of equipment is one of the most important issues in the development of medical inspection equipment. However, conventional models use external encoders on many drive axes to monitor the current position and detect misalignment, which hinders space saving.
2-phase/5-phase stepper motor PKP Series with encoder can be used to realize space saving in medical inspection equipment.
To Reduce the External Encoder by Replacing With a Motor With an Encoder
In the past, external encoders were mounted on the mechanism side, but this is no longer necessary and space saving mounting can be realized. In addition, the number of parts required for each axis is also reduced, which reduces man-hours and costs required for encoder installation during mass production.

Compact Encoder Equipped
The Encoder equipped in the 2-phase/5-phase stepper motor PKP Series with encoder is characterized by its high performance and compactness. The encoder of this product boasts high resolution and high angular accuracy, contributing to improved reliability of analysis results. Moreover, for a stepper motor with a frame size of 56.4 mm, the encoder is designed to be extremely compact, measuring only 16.5 mm × 20 mm.
When the frame size is 56.4 mm
- *The orange area in the dimensions diagram is the encoder section.
- *A convenient cable for wiring the encoder is sold separately.
