The motor parameters of Induction Motors are crucial when the Field Oriented Control Close loop torque/speed control is needed. More specifically, the rotor flux’s absolute position is determined mathematically using known speed, voltage and current, and a model representation of the motor’s main parameters. This blog shows how to determine these parameters.
The data sent from the Arduino are 0-3V and can be directly connected to the controller's RS232 input where it will be captured as valid 0-1 levels.The data at the output of the controller is +/-10V.
RFID tags and antenas are a cost effective and efficient method for determining the location of a robot along its track. CANOpen RFID reader/writers are a challenge to interface directly to a motor controller. This is because CANOpen is a master/slave architecture and both the RFID antena and the motor controller are slave devices. In a typical system, a CANOpen master (a PLC for example) must fetch data from the antena and send it to the controller.
Mixed Mode Steering, also known as tank style steering or skid steering, is easily achieved by selecting from a simple drop down menu in our dual channel controllers.
RoboCAN is a powerful networking protocol designed to allow RoboteQ products to easily communicate with one another. However, it can be a bit confusing initially to new RoboteQ users or those unfamiliar with CAN.
When operating brushless DC motors, knowing in real-time, and with precision, the position of the rotor is a prequisite to best performance in sinusoidal commutation. While numerous sensor techniques exist and are supported by Roboteq, Synchronous Serial Interface (SSI)
A Push Scooter is definitely a high volume consumer item requiring a dedicated motor controller and battery system. Before redesigning the controller and supporting electronics to fit it nicely into the scooter's base.
