CubeMars RI80 KV75 Motor with Hall Sensor

The CubeMars RI80 V2.0 KV75 is a frameless torque motor with an integrated Hall sensor, built for robotic joints, exoskeletons and other high-torque, direct-drive actuator projects.

Key features

• Frameless inner-rotor design lets the rotor couple directly to a shaft or turntable, removing the need for gears or belts.

• Delta-wound, 8 pole-pair motor rated at 24-48V, with a rated torque of 1.45Nm and a peak of 4.1Nm.

• 75 RPM/V (KV) rating suits low-speed, high-torque direct-drive control.

• Integrated Hall sensor gives rotor-position feedback for sensor-based FOC control.

• 85mm-diameter, 27mm-tall frameless housing weighing 411g, with a 40.5mm hollow shaft bore.
