  reluctance, and synchronous AC. However these motor types are not typically used for positioning applications. Since these motors are more typically used for velocity and or torque control we will leave a detailed discussion of them for another time. Positioning motors 101. Many engineers are adept...
• 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...
• Appliance motors turn green
  . For example, controllers, for those motors able to manage the high dynamic torque washing machines require, are expensive to create. An alternative motor type, such as a permanent-magnet synchronous motor (PMSM), makes it easier and cheaper to get the necessary performance. Sensorless control...
• 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...
• Smooth rotation
  and the position error during the constant velocity phase are virtually undetectable when using compensation. High-performance motion-control applications commonly use three-phase permanent-magnet synchronous motors, popularly known as brushless motors. These motors are typically operated...

  lower than that of permanent magnet synchronous motors. The difference arises because of the extra losses from the rotor winding currents and core magnetizing current. There is a third ac motor type called the reluctance motor. It is less widely used than either of the above motors but has a very...
• Motors Move Toward More Efficiency
  that excel at variable speeds just operate more efficiently than older models spinning at constant speeds. One indication of the difference comes from an analysis by International Rectifier Inc. which ranked losses of induction motors, synchronous reluctance motors, permanent-magnet synchronous motors...
