Overview

The Quanser QNET 2.0 DC Motor board is a versatile servo system designed to teach and demonstrate the fundamentals of DC motor control in a variety of ways. The system can be easily configured to control motor position and speed, as well as for modeling experiments.

  • Durable DC servo motor with no cogging
  • Removable inertia disk
  • Built-in PWM amplifier with linear response
  • High-resolution optical encoder to sense position
  • Hardware velocity measurement
  • System modeling and model validation
  • Speed and position control
  • System simulation
  • PID control
  • Error tracking
  • Disturbance rejection

The following additional components are required to complete your workstation, and are sold separately:

For LabVIEW

  • NI ELVIS II+
