Overview
CubeMars AK80-8 Motor (KV60) is a highly integrated BLDC motor module designed for compact, high-torque robotic joints. It supports an industrialized servo control mode and keeps an MIT power control mode for convenient, efficient, and accurate control with faster response. Marking on the unit: AK80-8 KV60 (CE, RoHS).
Key Features
- Integrated MIT power servo (modes integrated): servo control mode and power control mode
- High performance BLDC motor with high torque density and low cogging torque
- Industrial-grade crossed roller bearing (enhanced axial and radial impact resistance; improved reliability)
- Temperature sensor inside (real-time coil temperature monitoring; abnormal temperature protection support)
- Output encoder added: output shaft supports single-turn absolute positioning; no recalibration required
- Dual control mode (switch between two modes)
- Planetary reducer for stable output torque with limited size
Applications
- Humanoid robots
- Robotic arms
- Exoskeletons
- Quadruped robots
- AGV vehicles
- ARU robots
