  • Wedge drives precision elevator
    . "The inclined-plane approach offers superior performance to traditional -axis stages, " says Alan Petersen, Primatics' president. "The PZA offers a lower profile and easy access to all sides of the load. " Using a frameless motor eliminates a motor coupler and external motor, which reduces the table
  • Avoiding the runaround with direct-drive rotary motion
    Here's a look at the pros and cons of various direct-drive rotary systems. Manager Danaher Motion Wood Dale, Ill. Frameless DDR motors are best suited to high-performance applications where space is limited or weight is critical. Housed DDR motors are best suited for use on machines that do
  • Direct Drive (DDR) Rotary Table Construction
    Torque motors are also called "frameless" motors. They don't have housings, bearings, or feedback devices. In this sense the motor is a kit and meant to be part of the machine structure. Torque motors are designed as direct drives. They eliminate the need for gearboxes, worm-gear drives, and other
  • Observant resolvers
    advantages including providing position and velocity feedback with little or no phase lag, and estimations of motor acceleration and torque disturbance. The estimated acceleration is used to reduce problems with mechanical resonance, and torque disturbance feedback improves dynamic stiffness
  • Torque motors do the trick
    Direct-drive technology seems to be an ideal way to increase productivity, accuracy, and dynamic performance. It can also lower costs, simplify designs, and reduce wear. Torque motors are frameless kit motors consisting of a permanent-magnet rotor and laminated stator. A bridge keeps the rotor
