  • Getting to know stepper motors
    and amount, are controlled by stepper motors. Electronic pipettes are linear-stroke devices that utilize digital linear actuators to precisely control the amount of fluid being dispensed. The shaft of the actuator is coupled to a pipette fitted with a piston. A microprocessor controls the step rate
  • Stepper Motor Reference Design
    . Stepper motors are also found in industrial equipment such as robotics, electronic component handlers, testers, dispensers, and other manufacturing equipment. untitled AN155. STEPPER MOTOR REFERENCE DESIGN. 1. Introduction. timing. The low-pin count package has enough pins to. drive the stepper
  • Stepper phase current made easy
    , current-controlled method. Bipolar means the driver periodically reverses the polarity of voltage applied to the winding. Current controlled, as its name implies, varies the amount of current the motor sees. When power is first applied, the permanent magnet in the rotor of the stepmotor aligns with the magnetic
  • Brushless dc Motors in Medical Applications
    switch is replaced with electronic switches in BLDC motors with the polarity-reversal timing controlled by an electronic circuit. Ordinarily, BLDC motors use Hall-effect devices (HFD) to sense rotor position and control the electronic drive of the motor. However, by monitoring motor back- EMF, it’s
  • Determining MOSFET Driver Needs for Motor Drive Applications
    Electronic motor control for various types of motors represents one of the main applications for MOSFET drivers today. This application note discusses some of the fundamental concepts needed to obtain the proper MOSFET driver for your application. The bridging element between the motor and MOSFET
