Conical-rotor brake motors

• Product Description

  Simple, robust and reliable, these are the key characteristics of our KB conical-rotor brake motors. Their unique brake operating principle eliminates the need for separate control or additional switching elements. This is due to the mechanical connection between the brake and rotor. 

• Specification

  • High-performance motor
  • Motor output up to 55 kW (at 40% CDF)
  • 2, 4, 6 or 8 poles
  • Two-speed pole-changing motors
  • KBA for starting-and-stopping drives
  • KBF for direct line-fed travel motions
  • Extremely robust brake
  • No switching elements needed
  • No separate control needed
  • Long brake lining service life thanks to effective dissipation of heat generated by the brake (through large surface area of brake cover)
  • Short overall length and good heat dissipation (brake disc simultaneously forms the motor fan)
  • Two brake disc designs light for KBA motors, heavy and with increased moment of inertia for KBF motors
  • Extremely high switching frequency permitted
  • Resistance to temporary overload

• Warranty

• Shipping

• Returns
