CubeMars AK70-10 Actuator BLDC Motor Compact High-Torque Power


Description

The AK70-10 actuator integrates a high-performance brushless DC motor, a self-developed planetary reducer, an encoder, and an integrated drive, enabling smooth operation with high torque.Utilizing a portable drive solution, the AK70-10 Power Module supports both servo and MIT modes. It breaks away from conventions by achieving synchronized control of position, velocity, and acceleration, adapting to PID settings automatically and eliminating complexity to reach the target efficiently.CubeMars offers highly customizable motor modules.
