Dual channel brushless DC motor control

Roboteq's HBL2350 is capable of driving two brushless DC motors at 75 Amps and can accept commands from analog/pedal, R/C radio, USB or RS232 interface.

Roboteq, Inc. introduces the HBL2350, an intelligent controller capable of simultaneously driving two brushless DC motor up to 75 Amps each at up to 50 V.

Roboteq’s HBL2350 is the world’s first dual channel, high current brushless motor controller, allowing users to implement 2-wheel drive small electric vehicles, automatic guided vehicles (AGVs), balancing scooters, or any other high power brushless motor control application.

The controller accepts commands from either analog pedal/joystick, standard R/C radio for simple remote controlled robot applications, USB or RS232 interface. Using the serial port, the HBL2350 can be used to design fully or semi-autonomous robots by connecting it to single board computers, wireless modems or WiFi adapters.

The HBL2350 incorporates a Basic Language Interpreter capable of executing over 50,000 Basic instructions per second. This feature can be used to write powerful scripts for adding custom functions, or for developing automated systems without the need for an external PLC or microcomputer.

The controller's two channels can be operated independently or combined to set the direction and rotation of a vehicle by coordinating the motors on each side (tank-like steering). The motors may be operated in open or closed loop speed or position modes with a 1 kHz update rate. The HBL2350 can use the motor’s hall sensors or optical encoders to measure speed and travelled distance with high accuracy.

The HBL2350 features intelligent current sensing that will automatically limit each of the power outputs to 75A in all load conditions. The controller also includes protection against overheat, stall, and short circuits.

The controller includes up to 11 analog, 19 digital and 6 pulse inputs. Eight 1A digital outputs are provided for activating lights, valves, brakes or other accessories. The controller’s operation can be optimized using nearly 80 configurable parameters, such as programmable acceleration or deceleration, amps limits, operating voltage range, use of I/O, and more.

A free PC utility is available for configuring, tuning and exercising the motor. The controller can be reprogrammed in the field with the latest features by downloading new operating firmware from Roboteq’s web site.

The HBL2350 is built into a compact 9.0-inch L x 5.5-in. W x 1.6-in. H (228 mm x 140 mm x 40 mm), robust extruded aluminum case, which also serves as a heat sink for its output power stage. The large fin area ensures sufficient heat dissipation for operation without a fan in most applications.
