EMZ - Model Compact Series -Squirrel Cage & Slip Ring Motors
The EMZ compact series motors are designed to offer comprehensive solutions for a variety of standard applications. These motors are recognized for their high reliability, largely due to the selection of premium materials and the optimized design of their active components, which collectively reduce energy losses and enhance overall efficiency. They offer flexible application options with outputs reaching up to 2,000 kW, suitable for use with frequency converters, soft starters, or direct mains operation. The rib-cooled design of these motors includes the innovative dual-circuit cooling system, ensuring even temperature distribution and effective self-cooling. Different cooling types, such as IC 411, IC 416, and IC 511, are constructed to cater to specific cooling requirements, ensuring long motor lifespan and consistent performance regardless of motor speed. The robust, torsion-resistant frames further attribute to their durability. EMZ motors are particularly suitable for industrial sectors like wood and paper, steel and recycling, and cement and materials.
Compact three-phase slip ring motors
The EMZ compact series with our AKR and ASR motors can be used as an all-rounder for almost all standard applications and is characterised by a very high degree of reliability. The selection of high-quality materials and the optimised dimensioning of the active parts and the fans reduce losses and realise high efficiencies. The compact and torsion-resistant design in combination with an efficient cooling system guarantee a long service life.
Depending on the application, the motors of the EMZ compact series with outputs of up to 2,000 kW can be used very flexibly on the frequency converter, soft starter or even directly in mains operation.
IC 411
The rib-cooled EMZ motors with cooling type IC 411 are self-cooled and dissipate the heat loss to the outside cooling air via the ribbed motor housing and the end shields. The innovative dual-circuit cooling system with an internal cooling air circuit and an internal fan that is independent of the direction of rotation achieves an even temperature distribution in the motor.
IC 416
Cooling type IC 416 is constructively based on the proven cooling type IC 411, but differs in that the forced ventilation unit is mounted on the nondriving side and blows the external air axially over the cooling ribs, independent of the motor speed. This design guarantees a constant cooling capacity independent of the motor speed and is particularly suitable for variable-speed applications in combination with a frequency converter.
IC 511
EMZ motors with cooling type IC 511 are designed with concentric tube cooling, where the cooling tubes are rolled directly into the end walls of the stator housing. The steel-welded construction guarantees a uniform heat transfer from the inner cooling air to the outer cooling air circuit. Due to the compact design, the motors are very robust and torsion-resistant despite their low overall height.
