Cylindrical-rotor motors

Conical-rotor brake motors

1. Z Cylindrical-rotor motors

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

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 for travel applications with inverters
• ZBF for line-fed travel applications
• ZBE for continuous duty in energy efficiency class IE2
• ZBP for continuous duty in energy efficiency class IE3

Customised braking performance

• Motors with 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 utilizing differing spring strengths and quantities
• Various control modules for switching times to match application requirements

2. Conical-rotor brake motors

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. The result:

• particularly high braking performance
• approval for operation with extremely high switching frequencies
• two-speed pole-changing motors
• drives for starting-and-stopping applications and for direct line-fed travel motions
• resistance to temporary overload
• KB motors can be connected to gearboxes via a coupling.

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
