slip-ring motors-MEBSGR series

Product catalog summary

Preface
The MEBSGR Series motors are engineered for high-demand applications requiring significant start-up and breakaway moments, ideal for industries such as cement, paper, water, and steel. They are commonly used in mills, crushers, and shredders.

Features
These motors provide excellent value, high power efficiency, low operating costs, reliable bearings, smooth operation, low maintenance, and minimal noise emissions. They are constructed with windings in temperature class F using the VPI method.

Standards
The motors adhere to European standards EN60034 and IEC34.

Construction
They feature a torsionally rigid grey cast iron housing with optimal cooling and self-cleaning properties.

Types and Protection
Available in type IM B3, with special versions available upon request. They have an IP 55 protection rating.

Cooling and Insulation
Utilizing cooling type IC 411 with bi-directional external fans, the insulation is tropicalised to temperature class F, ensuring slow aging and high mechanical stress resistance.

Bearings
The motors use grease-lubricated rolling-contact bearings, with options for reinforced bearings for belt drives, using high-quality lithium-soap grease.

Vibration and Noise
Motors meet vibration severity grade A and have low noise levels, with sound pressure levels detailed in datasheets.

Paint Finish
The standard paint is RAL 1016 "sulphur yellow," with custom finishes available.

Voltage Ratings and Ambient Temperature
Nominal voltages are 380-420V at 50Hz and 440-480V at 60Hz, with a ±5% tolerance. Designed for ambient temperatures between -20°C and +40°C, with power reduction required above 40°C.

Type Ratings and Overload Capability
Type ratings are for continuous operation at 40°C and up to 1000m elevation. Motors can handle 1.5 times the nominal current for up to two minutes once per hour.

Terminal Boxes and Slip Ring Compartment
Frame sizes 250 and 280 have two terminal boxes, while sizes 315 and 355 have a shared box. The slip ring compartment is sealed to prevent carbon dust contamination.

Motor Protection and Testing
Motors include temperature monitoring with PTC sensors. Factory tests include winding resistance, insulation resistance, no-load, short-circuit, direction of rotation, vibration, and noise tests. Additional tests are available on request.

Specifications
The motors are equipped with a thermostat for the stator winding, utilizing PTC thermistor temperature sensors. These sensors are installed in the stator winding, with connectors terminating in the terminal boxes at the drive end. Additional sensors and transmitters are available upon request.

Testing Procedures
Motors undergo a standard factory test including winding resistance measurement, insulation resistance test, no-load test, short-circuit test, direction-of-rotation test, vibration severity measurement, visual acceptance, and noise measurement. A test report is compiled for each motor and can be included with the documentation upon request. Additional tests can be performed as needed.

Datasheets
The motors are part of the MEBSGR series, with specifications including IP 55, IC 411, and type IM B3. They operate at 400 Volt / 50 Hz with options for 4-pole, 6-pole, and 8-pole configurations. The temperature class is F, suitable for an ambient temperature of 40°C.

Technical Data
The document provides detailed technical data for various motor types, including power (kW), speed (min-1), current (A), power factor (cos φ), efficiency (η), torque (Nm), voltage (V), and mass (kg). This data is organized by motor type and pole configuration.
