Cylindrical-rotor motors

More 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 72 HP (45 kW)
• 2, 4, 6 or 8 poles
• Two-speed motors
• ZBA/ZNA for travel applications with inverters
• ZBF for line-fed travel applications
• ZBE/ZNE for continuous duty in energy efficiency class IE2

Customized braking performance

• Motors with or without a brake
• Specified brake torques from 0.6 to 496 ft-lbs (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 utilizing differing spring strengths and quantities
• Various control modules for switching times to match application requirements

Many further options and accessories

 

Motor and gearbox combinations

Direct drive input

Gearbox and Z cylindrical-rotor motor combinations using end caps

Coupling connection

Gearbox and motor combinations with Demag coupling shaft end (Z cylindrical-rotor motors or KB conical-rotor brake motors) using intermediate flange and roller spider coupling
