MyActuator CEM-25 Cycloidal Actuator (CAN & EtherCAT)
MyActuator CEM-25 Cycloidal Actuator (CAN & EtherCAT)
🤖 Compact cycloidal joint - high precision and shock resistance in a small frame.
🔍 Product Overview
The CEM-25 is an integrated cycloidal actuator: a cycloidal reducer paired with a BLDC motor, FOC driver and encoder. Cycloidal drives shine where joints see shock and impact loads - they offer excellent overload/shock resistance, small backlash and high torque density, making them a top choice for dynamic humanoid and legged-robot joints. Supports both CAN and EtherCAT for high-speed synchronised control.
