Special Applications

Boring, Drilling, Grinding, and Machining. Maximum Precision for a Range of Critical Functions.

When the difference between success and failure can be measured by microns, you need Perske motors. Perske offers a line of multipurpose motors that meets the demand for extremely fine machining tolerances.

Industry applications that require Special Application Motors include:

  • Aerospace manufacturing
  • Automotive industry metalworking and finishing
  • Medical and dental equipment
  • Plastic industry
  • Woodworking finishing

Overall features for precision, performance, and durability:

  • High-speed performance motors reach speeds ranging from 3,600 RPM to 30,000 RPM
  • Motor power ratings are rated for continuous duty
  • Lifetime lubricated, high precision bearings
  • Motors are designed for exacting and precise grinding applications on materials including wood, metals, and composites
  • Narrow motor design allows for small axial distances between the grinding wheel and machine shaft for ultimate precision when attaining extremely small tolerances
  • Careful dynamic balancing to ensure micron-quality run-out tolerances and precision cutting performance
  • Varying collet capabilities and types accommodate different grinding wheel sizes with a maximum tool shank up to 1 inch (depending on motor design)
  • Direct tool mounting options include outside tool shank with inside bore, collet and covernut, and HSK-C
  • On boring/drilling-specific motors, shaft design can incorporate an outside taper, inside bore, and outside thread or a collet and covernut

Tool Systems
  • Saw collars/flanges with threaded nut (RH or LH)
  • HSK-C
  • Hydro-clamp chuck system
  • Cylindrical shaft with or without key
  • Cylindrical shaft with or without key and outside thread
  • Cylindrical shaft with or without key and inside thread

Frequency

  • 60 HZ (3,600 RPM) standard (Some motors are capable of running up to 7,200 RPM)
  • Electrical performance data (HP) are only valid for the stated constant frequency Voltage
  • 230/460V standard according to DIN/VDE regulations; however, other voltage options are available including 575V for Canada

Bearings

  • Lifetime lubricated, high precision bearings (where required)
  • Drive end bearing is fixed and non-drive end bearing is self-aligning
  • With heavy tooling, double bearing arrangements are recommended for front bearing position to eliminate axial shaft play

Features

  • TEFC motors are self-ventilated with a built in fan which works most effectively at the motor’s maximum operating speed
  • Labyrinth seals at both ends of the motor to protect against dust or particle penetration into the motor when under power
  • Motors are balanced to a vibration speed of Veff = 1.8 mm/sec at zero load and rated operating speed
  • Terminal box can be located on right or left side pending customers preference
  • An electromechanical brake can be integrated as an option
  • Motors are available according to NEMA standards
