QuimMotor DC

Dual Brushed (DC) motor controller with CAN interface, Brakes and Encoder inputs.

The QuimDC is an electronic board designed to control two sensored DC motors or also called “brushed” motors. It includes both the power electronic driving the motors, and the digital electronic integrating a micro-controller that embed the control system. The QuimDC can operate in 2 ways, in standalone mode, in which the product is used independently in a particular application or in an integrated mode in which the QuimEC is plugged into a QuimBox to offer a more integrated and complete solution for robots or mechatronics systems (see www.quimesis.be for more information).

Ideal for torque, speed and/or position motor control applications. Each motor is controlled with a full H-bridge embedded in the L6201PS driver and with independent quadrature encoders inputs (QEI).  The controller measures also the instantaneous current of both motors for torque control and/or current limitation.

Besides, for robotic platform requiring a precide positioning measurement, the board has two additionnal quadrature encoders interfacing, that can be interfaced to independant freewheels. The QuiMDC also has a motor brake interfacing, which make it a complete solution for interfacing with a DC actuation system.

Using CAN bus or serial-to-USB interface, the controller receives commands from the user to define different parameters or orders.
