Description
The frame is rectangular, without a jacket, and ventilation is independent, so full torque is kept over the entire speed control range. The rotor is squirrel-cage, with class H thermal insulation. The version is horizontal or vertical, in all standard protection and cooling methods; for hazardous zones 1 and 2 there are purged versions Ex px and Ex pz. The motor is built on a flexible platform and adapted to the customer, in particular to existing foundations. It complies with IEC and DIN EN standards and EU directives. According to the manufacturer, the machine has high torque in a small size, high overload capacity, low moment of inertia and lower weight compared with standardized motors. Thanks to optimized operation from a converter, it can replace a DC motor in an adjustable drive. A typical application example is hoist motors of container handling cranes of 300–650 kW.
How to choose
Selection starts with power and shaft height. Clarify the lower limit of the range, since the brochure states 50 kW and the catalog 150 kW at 1500 rpm. For high-speed machine tools and test stands, see the turbo version up to 9000 rpm. In zones 1 and 2 order the Ex px or Ex pz version, and for an existing foundation the motor is adapted in dimensions.

FAQ
What power do A5L series motors have?
150–2500 kW at 1500 rpm. The brochure states the lower limit as 50 kW.
Which shaft heights and speeds are available?
Shaft heights of 200, 250, 315, 400 and 450 mm, up to 9000 rpm in the turbo version.
Can a DC motor be replaced?
Yes, according to the manufacturer, the motor replaces adjustable DC machines of medium power, since full torque is kept over the entire speed range.
Is there an explosion-protected version?
Yes, for zones 1 and 2 with purging, Ex px and Ex pz.
How is the motor cooled?
By independent forced ventilation, so cooling does not depend on the shaft speed.
