MEBKGR SERIES

Product catalog summary

Standards: The motors adhere to IEC and EN standards covering electrical and mechanical specifications, including guidelines for terminal markings, starting performance, standard voltages, dimensions, protection degrees, cooling methods, construction types, noise limits, and vibration severity.

Construction: The motors are constructed with a grey cast iron housing and moulded legs, enhancing cooling and self-cleaning.

Types of Construction: Available types include IM B3, IM B35, IM V1, and IM V15, with additional types available upon request.

Degree of Protection: Standard protection is IP55, with other options available upon request.

Cooling: The standard cooling method is IC 411, with IC 416 available for special applications.

Insulation: Motors are built to temperature class F, with thermal stress in class B, offering a power margin and reduced aging. Optional insulation in class H is available.

Bearings: Standard motors feature grease-lubricated bearings with re-lubrication devices, using high-quality bearings and lubricants.

Vibration and Noise: Motors comply with EN 60034-14 vibration requirements and are designed for low noise levels.

Paint Finish: Motors are coated to meet moderate climate group requirements, available in RAL 7030 or RAL 1016 colors.

Voltage Ratings: Available at 50 Hz (400V/690V) and 60 Hz (440-480V), with other voltages upon request.

Ambient Temperature: Designed for -20°C to +40°C, with power reduction required for higher temperatures.

Type Rating: Refers to continuous operation at nominal voltage and frequency, with power reduction for higher elevations.

Overload Capability: Motors can handle 1.5 times nominal current for up to two minutes.

Frequency Converter Operation: Suitable for up to 500V, with modifications available for higher voltages.

Terminal Boxes: Standard position is on top, with customizable cable entry options.

Motor Protection: Includes thermistor temperature sensors, with additional sensors available.

Accessories and Tests: A wide range of accessories and extensive factory testing are available, with detailed documentation upon request.

Overview: This document is a technical datasheet from MENZEL Elektromotoren GmbH, detailing specifications for the MEBKGR series of electric motors, including models, power outputs, efficiency, and other technical parameters.

Specifications: The MEBKGR series motors are available in configurations based on the number of poles (6, 8, and 10 poles), operating at 400/690 V and 50 Hz, with a protection degree of IP 55 and cooling type IC 411/416. The insulation class is F, and the thermal class is B, suitable for an ambient temperature of 40°C.

Performance Data: Detailed tables provide power (kW), speed (min-1), current (A) at 400 V and 690 V, efficiency (%), power factor, starting current (IA/IN), starting torque (MA/MN), maximum torque (MK/MN), inertia (kgm2), and weight (kg) for each motor model. Efficiency ranges from 94.7% to 97.0% depending on the model.

Additional Information: Higher output models are available upon request. Technical modifications and errors are subject to change.
