Unitree A1 Motor - Integrated Motor and Controller
Regular price
€0,00
The Unitree A1 Motor is a highly integrated motor designed for applications such as foot robots and other large-load machinery and equipment. It combines the motor body and controller in one unit, reducing connecting lines and supporting plug-and-play quick disassembly. The motor supports sensor feedback and control instructions, with a maximum instantaneous torque of 33.5 N.m and a maximum joint rotate speed of 21 rad/s. Its closed design helps prevent debris from entering the motor, while built-in temperature monitoring helps prevent damage caused by temperature abnormalities.
Highlights
- Ultra-thin fuselage design with a fuselage weight of 605 g.
- Maximum instantaneous torque is 33.5 N.m.
- Maximum joint rotate speed is 21 rad/s.
- Integrated motor body and controller reduce connecting lines and support plug-and-play quick disassembly.
- Closed design helps prevent debris from entering the motor.
- Oversized industrial-grade crossed roller bearings are used for axial impact resistance, high precision, and long life.
- Built-in temperature monitoring sensor helps prevent damage caused by temperature abnormalities.
- FOC control is stated to provide low torque ripple, low noise, and smoother operation.
- Motor sensing feedback includes torque, angle, angular velocity, angular acceleration, and temperature.
