RoboClaw 2x160A Motor Controller - two-channel DC motor controller

Description

RoboClaw 2x160A Motor Controller is a two-channel DC motor driver that can independently control the operation of two motors. The control can be done via USB port, serial TTL interface, signal from RC receiver or through analog input. The controller has built-in decoder quadrature encoders, which allow easy implementation of the closed loop of engine speed control. The option of energy recovery during engine braking, resistance to sudden changes in speed (at high engine revolutions), and the control system of battery charge and cut-off in case of too deep discharge should be considered as an additional, noteworthy option. These are very convenient and useful properties that will certainly simplify the construction of not one mobile construction.

The presented version of the controller has two channels, each of which has a capacity of 120 A at constant power consumption, while the maximum instantaneous current consumption is 160 A. The voltage supplying the motors ranges from 10.5 to 60 V.

The RoboClaw 2x160A version is much larger and heavier than the other modules from the 2-channel RoboClaw family. The controller is completely enclosed in a metal casing that has a series of tabs that help it function as a large heat sink. Power input and connectors for motors are available via external screw terminals and three "Molex" connectors for control pins, user feedback and I / O.
