RoboClaw ST 2x45A Motor Controller


The Roboclaw 2x45A motor controller can supply two brushed DC motors with 45 Amps continuous and up to 60 Amps peak. With its multi mode interface it can be controlled from USB, RC radio, serial devices, analog and or microcontrollers such as an Arduino or Raspberry Pi. Dual quadrature encoders with up to 19.6 million pulses per second are supported. In addition, a wide range of sensor inputs including potentiometers and absolute encoders are supported. Roboclaw's close loop functionality creates absolute control over speed, velocity and direction regardless of loading changes. At the heart of Roboclaw is a high performance motion control intelligence which achieves a higher precision of control while providing better motor performance in open or closed loop modes. With Roboclaw's synchronous regenerative capabilities it will charge a supply battery during slow down or breaking action. With it's advanced circuitry it can also change direction during full throttle without damage! Roboclaw also incorporates a lithium cutoff mode protecting batteries from damage. We offer two versions of the 2x45A controller as shown below. This version offers screw terminals for all I/Os.
