HBL2350


Product Description

Roboteq’s HBL2350 is a high-current, dual channel controller for hall-sensor equipped Brushless DC motors. The controller uses the position information from the sensors to sequence power on the motors’ 3 windings in order to generate smooth continuous rotation. The controller also uses the Hall sensor information to compute speed and measure travelled distance inside a 32-bit counter. The motors may be operated in open or closed loop speed mode. Using low-cost position sensors, they may also be set to operate as heavy-duty position servos.

The HBL2350 accepts commands received from an RC radio, Analog Joystick, wireless modem, or microcomputer. For mobile robot applications, the controller’s two motor channels can either be operated independently or mixed to set the direction and rotation of a vehicle by coordinating the motion of each motor.

Numerous safety features are incorporated into the controller to ensure reliable and safe operation. 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.
