Details

CubeMars AK45-10 KV75 combines the motor, planetary gearbox, and driver in one compact module to save installation space.

A three-in-one architecture brings the motor, gearbox, and driver together for a cleaner mechanical layout and simpler integration.

Designed for lightweight robotics builds, with a 260 g module weight and up to 7 N·m peak torque.

Low-noise operation supports ultra-smooth motion and fine positioning control for jointed robotic mechanisms.

The 10:1 planetary reduction boosts torque output while keeping backlash tightly controlled for responsive joint control.

Integrated wiring keeps setup plug-and-play, with UART and CAN ports plus a 14-bit single-turn absolute encoder for feedback.
