Roboteq has introduced the RGBL1860 and RGBL1896 motion controllers for brushless DC motors. They are suitable for electric vehicles, material handling robots, electric boats, or agricultural robots.
The products feature several analog, digital, and pulse I/Os, which can be remapped as command or feedback inputs, limit switches, or other functions. The controllers accept commands received from an RC radio, analog potentiometer, wireless modem, PLC, or microcomputer. Using a CAN network, up to 127 controllers can be networked at up to 1 Mbit/s.
The controllers operate in trapezoidal or sinusoidal commutation. In trapezoidal mode, they use hall sensors that are typically built into the motor. In sinusoidal mode, they use all types of rotor sensors, including Sin/Cos, resolver, hall sensors, quadrature encoders, and SSI-compatible absolute encoders. In sinusoidal mode, the controller uses field oriented control in order to operate with optimal efficiency, said the company. The motors may be operated in open or closed-loop speed mode, position mode or in torque mode. The controllers' operation is extensively automated and customized using Basic Language scripts. The product is able to be configured, monitored, and tuned in real-time using a Roboteq's free PC utility.
