Induction motor parameters calculation

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.

CANopen is a communication protocol that uses several classes of "objects" for managing a network of motor controller,s sensors, PLCs and other devices. A complete description of CANopen can be found on Wikipedia.

Building an R2D2 Replica

Star War's R2D2 has inspired a generation of engineers and engineers-to-be to pursue the field of Robotics. If you ever dreamed of having your own droid, this use blog article will shows how you could.

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.

Resolvers are absolute angle sensors that use entirely passive transformer technology. Resolver offer reliability benefits over other technologies and are perfectly suited in extreme temperature, oily, dusty or even radio active environment.

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)

 When a motor is spinning faster than it would normally at the applied voltage, such as when moving downhill or decelerating, the motor acts like a generator.
