Overview
HONPINE HPJM-RE30-40-PRO Motor is a compact motor module with reduction gearing and a hollow-shaft absolute multi-turn encoder. It supports a 24-48V supply and CAN communication, with two reduction ratio options: 1:51 and 1:101.
Key Features
- Reduction ratio options: 1:51 or 1:101
- Communication bus: CAN
- Encoder: Hollow Shaft Absolute Multi-turn Encoder (17-bit per motor revolution, multi-turn counter 2^16 / 65,536)
- Through hole diameter: 6mm (single encoder CAN/CANopen; dual encoders CAN/Ethercat)
