  • A New Absolute Inductive Transducer for Brushless Servomotors
    Today, frameless brushless (pancake) resolvers are commonly used on AC and brushless DC servomotors to provide commutation, position, and velocity information to the servo controller. These angular position transducers give a constant signal representing the absolute position of the motor shaft
  • Torque motors do the trick
    to frame sizes for conventional brushless-dc servomotors. For each diameter, there are several axial lengths, so engineers have a range of sizes to satisfy torque requirements for given applications. A torque motor is part of this rotary table Torque motors have been around since at least 1970
  • Snake-oil specs spell trouble for motor sizing
    calculating worst-case conditions. Parameters for brushless dc motors powered by sine-wave drives differ from those controlled by conventional six-step dc pulse drives. And because a major trend is toward more brushless motors with resolver feedback, manufacturers are beginning to provide servomotor
  • Everything you always wanted to know about slab resolvers but were afraid to ask....
    is an unhoused or frameless slab resolver. However, to all intents and purposes, a pancake resolver is the same as a slab resolver and the terms are used interchangeably. You may also see or hear the term 'brushless resolver'. This simply means that there are no electrical connections to the resolver's
