Description
The open design with cooling independent of speed makes it possible to work in continuous duty over the whole speed control range and to obtain high power density in a compact frame. The motors have very high torque density, a low rotor moment of inertia and high overload capability, which means dynamic acceleration and braking. Various mounting versions, supply voltages and winding variants are provided. Individual adaptation to the mechanical and electrical requirements of a specific installation is also possible. The motors are made by the plant in Wernigerode, Material Handling division, and the manufacturer stresses long operation even in heavy conditions.
How to choose
The site has no detailed data on voltages and efficiency classes of the series, so parameters are selected on request. The series suits drives of cranes, material handlers, conveyors and other machines with frequency control where high torque is needed in a limited volume. For heavy industry, mechanical engineering and complex conveyor systems it is chosen by frame and power. If the environment is dusty or damp, protection degree IP23 may not be suitable, and then enclosed versions are taken.

FAQ
What is the maximum power and frame of IP23 motors?
The series goes up to frame 450 with rated power up to 1650 kW.
Can IP23 motors be fed from a frequency converter?
Yes, they are oriented from the start towards operation from a frequency converter. Cooling is independent of speed, so continuous duty is possible over the whole control range.
What equipment are these motors intended for?
First of all for material handling equipment, and also heavy industry, mechanical engineering and complex conveyor systems. Examples are drives of cranes and material handlers.
Are the voltages and efficiency class of the series given on the site?
No, there is no detailed data. Voltage, winding variant and other parameters are selected on request for the installation.
