MARATHON NEMA High voltage permanent magnet DC motors are typically used with and SCR (thyristor) controller in applications requiring adjustable speed and constant torque throughout the speed range. They are also widely used in applications requiring dynamic braking or adjustable speed/reversing capabilities.


  • Totally enclosed fan cooled
  • 5/8" shaft output diameter
  • Class F insulation
  • NEMA C-Face with removable rigid base
  • Oversized brushes for extra long life
  • Permanently lubricated sealed ball bearings
  • Linear speed/torque characteristics over entire speed range
  • High starting torque, high peak current capability
  • Usable on PWM type DC adjustable speed drives at higher HP rating
  • Easy brush access with unique brush holder design
  • UL Recognized and CSA Certified

Mechanical Specifications: Low profile space-saving design. Unique brush holder design provides easy access to brushes and integral constant pressure brush/spring assembly for servicing. Large oversized brushes assure longer brush life. Heavy-duty, stamped steel, bolt-on base (removable). NEMA C face mounting at no additional cost. Rugged die cast aluminum endshields with cast iron bearing inserts. Permanently lubricated sealed ball bearings. May be converted NEMA 48 base using a modification kit.

Electrical Features: Input power of 115 or 230 volts rectified AC when used with an appropriate SCR control. Linear speed/torque characteristics over entire speed range. High starting torque for heavy load applications. Capable of dynamic braking for faster stops. Reversible rotation with simple two-lead connection.

These motors may also be used with PWM (pulse width modulated) type DC adjustable speed drives at a higher HP rating.
