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 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

Product information

The benefits at a glance

For both motor output and braking capacity: you benefit from a range of outstanding advantages with our Z cylindrical-rotor motors.

Strong motor output
  • Motor output up to 45 kW
  • 2, 4, 6 or 8 poles
  • Two-speed pole-changing motors
  • ZBA/ZNA for travel applications with inverters
  • ZBF for line-fed travel applications
  • ZBE/ZNE for continuous duty in energy efficiency class IE2
Customised braking performance
  • Motors with or without a brake
  • Specified brake torques from 0.9 to 680 Nm
  • Two brake sizes available for each motor frame size
  • ZB cylindrical-rotor motors fitted with disc brakes (held by springs when no voltage is applied)
  • Finely graded brake torques by utilising differing spring strengths and quantities
  • Various control modules for switching times to match application requirements
