  • What are Rail Brakes and When Should You Use Them?
    The servo and stepper motors that drive linear motion systems often include a braking function, or, in the case of stepper motors, detent torque that helps prevent the motor (and, therefore, the load) from moving when powered off. But in some applications, a secondary brake is required - either
  • Breakthrough in Brake Squeal Prediction Helps to Eliminate Noise Problems Early in Design Process
    (OEMs) and suppliers face. A recent breakthrough is an integrated. approach to brake squeal prediction: It incorporates bidirectional computer-aided design. (CAD) connectivity, automated meshing and connectivity, flexibility to use a linear and/or nonlinear. solver, parametric and sensitivity studies
  • Using the dsPIC30F & dsPIC33F DSCs for Sensorless BLDC Control
    braking current to regulate DC bus The BLDC motor is usually operated with one or more voltage. rotor position sensors since the electrical excitation Commutation scheme allows up to 30° phase must be synchronous to the rotor position. For reasons advance to be linearly introduced as the speed of cost
  • Piezo Motors: Principle of Operation for Engineers
    devices. Travel can be linear or rotary, depending on the coupling mechanism. Closed loop servo control can be provided with standard off-the-shelf servo controllers, or with the Nanomotion servo controller that offers full PID control at 20 kHz servo rate. Further, the motors can operate in actuation
