HEX 4310 Data Center

中文 | English

The HEX43xx series motors are integrated joint motors designed by HexFellow specifically for the embodied robotics industry. The series uses a planetary reduction system and offers advantages such as impact resistance, high torque transparency, low friction, and high cost-effectiveness. The motors feature integrated drive and control with CAN-FD communication, and support hardware timestamping, synchronization, MIT control, one-to-many control, and other functions.

Technical Specifications

Motor Characteristics

Motor Features

  • Dual encoders with single-turn absolute position on the output shaft, no loss of absolute position on power failure; integrated motor and driver design with compact structure and high integration.
  • Feedback of motor speed, position, torque, motor temperature, and other information via CAN-FD@5Mbps.
  • Support for sending control commands to multiple motors simultaneously with a single CAN message, enabling one-to-many control.
  • Customizable return messages (via CANopen PDO mechanism).
  • Support for multiple control modes including position mode, velocity mode, torque mode, MIT mode, and more.
