  • Mighty motors
    Permanent-magnet synchronous motors eliminate gearboxes. Vice President and General Manager Industrial applications requiring high torque at low speeds typically use synchronous motors with reducers. Induction motors generate plenty of torque, but not at low speeds. However, new synchronous motor...
  • AC Motors
    in a large drop in rpm for a fairly small change in load. Reduced speed is provided down to about 50% rated speed, but efficiency is low. Multispeed motors: Consequent-pole motors are designed for one speed. By physically reconnecting the leads, a 2:1 speed ratio can be obtained. Typical synchronous speeds...
  • Dynamics of Hybrid Stepper Motors
    that the motor can overcome to accelerate a stopped load to synchronous speed. Trying to accelerate faster using more torque than the rated pull-in value will again make the rotor skip steps. Maximum speed is defined as the speed at which the available torque falls to zero. Resonance problems make it difficult...
  • Dc motor impersonators
    voltage, frequency, and rpm. The stator windings of the motor are arranged such that a rotating magnetic field is created when energized with three-phase ac currents. The rpms at which the magnetic field rotates is called the synchronous speed. The rotor of an ACIM must turn at a slightly slower rpm...

  • Brushless dc Motors in Medical Applications
    for more-efficient, compact, and reliable medical equipment has put BLDC motors on the prescription list for a variety of applications. By definition, a brushless-dc motor is a synchronous electric motor powered by a dc-power source. While derived from the brushed-dc motor, an electronic commutation...
  • Field-oriented control for motors
    Microprocessor control lets variable-speed PMSMs save energy. Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use advanced motor- control techniques...
  • How software assists designing motors and generators
    . To calculate output power at a given rotor current, users solve the inverse problem of calculating torque for a synchronous motor at a preliminary estimated rotor current and load angle (rotor position). The instantaneous vector potential distribution is for a 3-hp, four-pole switchedreluctance motor...
  • Basic Gyroscope Spin Motor Excitation Requirements For USD Gyroscopes
    This applications note discusses basic gyroscope spin motor excitation requirements for many models of US Dynamics miniature Rate Integrating Gyroscopes (RIG) and Rate Gyroscopes. Most US Dynamics miniature gyroscopes utilize 2 phase synchronous (hysteresis) motors to drive the gyroscope inertia...
  • EC Motors, The Extended Arm Of Automotive Electronics (.pdf)
    synchronous operation. The freely accessible rotor is ideally suited for example. to carry various impeller blades as a fan drive. The motor and fan specialist ebm-papst of St. Georgen, Germany,. specially manufactures therefore a variety of different fans for the automotive industry. It is important...
