Strong motor output up to 45 kW

Z Cylindrical-rotor motors

Perfectly engineered braking performance

Our Z cylindrical-rotor motors perform a wide variety of industrial drive tasks – reliably and effectively. They are suitable for a broad range of applications, offering outstanding performance:

  • motor output up to 72 HP (45 kW)
  • inverter-fed drives for travel applications, line-fed travel and continuous operation
  • specially designed to match our range of gearboxes
  • simple project engineering
  • high drive efficiency
  • software tools to calculate drive requirements according to specified physical characteristics

See a comparision between the Z-cylindrical-rotor motor, KBA and KBF motors on our blog.
