  • Application Example - Custom Chiller for Automotive Industry
    An automotive OEM manufacturer needed a chiller to integrate with their OEM machines. The main requirement from the OEM was to cool two separate circuits of oil, each of which must be controlled separately. One circuit was used for cooling a spindle motor and the other circuit was used to cool
  • Motor Eliminates Cogging Torque for Ultra Smooth Servo Track Writer
    Air bearing spindles for such demanding and close-tolerance applications as wafer Manufacturing and handling equipment and servo writers require especially smooth velocity. Typically, we use an 8-pole slotted brushless DC (BLDC) motor in these applications. However, for a recent servo writer
  • 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
  • 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...
  • 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
  • Medical Device Link .
    tools. With high-efficiency motor power of 11 or 7.5 kW per spindle, the machine offers up to 22 or 15 kW of cutting power for shaft-work turning with synchronised spindles. The three milling motors can have either 7.1 or 2.2 kW of output power. Other elements of machine construction include
  • Regenerative Power Units Save Energy
    When an electric motor is driven by a variable frequency drive (VFD), electric power delivered to the motor is regenerated while the motor decelerates by applying negative torque to the motor shaft. Usually energy storage capacity inside the VFD is very limited so regenerative energy should
