  • Positioning Capabilities of Ultrasonic Motors
    While conventional positioning systems convert the rotary motion of a motor into linear motion using a spindle, PILine (R) positioning systems are based on a special direct drive. This completely eliminates backlash and play and enhances the response time and positioning accuracy. Furthermore
  • Motor Eliminates Cogging Torque for Ultra Smooth Servo Track Writer
    application the spindle nose deviation error of 0.15-micro-inch (3.81 nanometers) was unacceptably high. While looking for a solution, we discovered a new slotless BLDC motor technology without wire windings developed by ThinGap, Inc., which minimizes cogging torque and torque ripple to deliver extremely
  • Medical Device Link .
    rotary tables. Speeds up to 250 rpm are possible on the rotation axis and up to 150 rpm on the swivel axis, with a swivel range of +-110 . A concrete polymer base provides rigidity, vibration dampening, and high thermal stability. Spindle motors are liquid cooled with hybrid ceramic ball bearings
  • Linear Motors Offer Precise Positioning and Highly Dynamic Response for Many Motion-Control Task
    Linear Motors Improve Speed, Positioning Linear motors offer precise positioning and highly dynamic response for many motion-control tasks. For machine tools, these include not only rapid traverse, but slow, constant-speed movement of machine heads, spindle slides, tool-management systems
  • Smart Computing Article - Diskette Drives
    is they're technologically simple. A diskette drive basically has three parts: a spindle motor, which spins the diskette when it is inserted into the drive; a stepper motor, which positions the head that reads data from and writes data to the diskette; and a controller card, which contains the circuitry
  • Shock, awe, and vibration
    but to pack sensitive electronics and tiny mechanical components more closely. Within these tight quarters, however, there's often little room left for shock mounts and vibration isolators. These components protect printed-circuit boards, LCDs, disk-drive components (spindle motors, heads, head arms
  • Advanced bearings for high-speed machining
    of precision machine tools, few topics receive more attention than high-speed machining. Cutting metal at higher speeds increases productivity. But to run faster without losing quality or reliability, the spindle, motor, and bearing system must provide the torque, rigidity, and accuracy for cutting
  • Higher rotational speeds for micro gas turbines
    High speeds are not only required in applications where a motor is used to drive a compressor, micromachining spindle or a mirror. More and more high-speed generators, with speeds of 300,000 rpm and beyond...
