Roboteq’s VSX1850 is a high-current controller for Separate Excitation DC motors. The controller is composed of a unidirectional half-bridge capable of up to 500A for the motor’s armature, and a 25A bidirectional power bridge for the motor’s excitation (field).
The controller accepts commands received from a RC radio, Analog Joystick, wireless modem, or microcomputer to coordinate the armature and field bridge power so that the motor will move in a precisely controlled manner in the forward or reversed direction. The motor may be operated in open or closed loop speed mode. Using low-cost position sensors, it may also be set to operate as a heavy-duty position servos.
The controller's operation can be extensively automated and customized using Basic Language scripts. The controller can be configured, monitored and tuned in realtime using a Roboteq’s free PC utility. The controller can also be reprogrammed in the field with the latest features by downloading new operating software from Roboteq.
Detailed description of the technology and features common to all Roboteq controllers can be found on the Technology page.
