Roboteq (www.roboteq.com) has unveiled an all-new smart controller that can simultaneously drive two brushless DC motors each about 50V and 75A — the HBL2350.
The first in the group of high current, dual channel brushless motor controllers, HBL2350 can be utilized to control automatic guided vehicles, two-wheel driven small electric vehicles, balancing scooters and other applications that require high power brushless motors.
The controller receives commands either through an analog pedal or a joystick. Its standard R/C radio allows for easy robotic applications by means of remote control through USB or RS232 interface.
The controller can execute over 50,000 basic instructions in 1s through an integrated basic language interpreter. This feature is particularly helpful for adding custom functions through scripts without needing an external PLC or microcomputer.
The motors can operate in an open or closed loop position with an update rate of one kHz. Meanwhile, optical encoders can be used to measure the speed and travelled distance with high accuracy. The controller’s smart current sensing capability narrows down the highest power output to 75A under all load forms.
The controller can also hold up to 11 analogue inputs, six pulse and 19 digital and deliver up to eight 1A digital outputs, which can be utilized for activating brakes, valves, lights and other instruments. Housed in a strong aluminum case, the controller measures 228 mm x 140 mm x 40 mm.
