Product catalog summary
Overview: This document is a technical catalogue for explosion-protected three-phase low-voltage squirrel-cage motors with increased safety, covering power ranges from 0.12 to 13.5 kW. It includes specifications, standards, tolerances, mechanical and electrical design details, and user instructions.
Specifications: The motors are designed for increased safety (EEx e) and comply with various standards such as DIN EN 60034 and IEC 34. They are suitable for use in potentially explosive atmospheres, classified under apparatus group II, category 2, with temperature classes T1 to T3. The motors have degrees of protection ranging from IP54 to IP65 and are designed for ambient temperatures between -40°C and +40°C.
Mechanical Design: The motors are available in sizes 63 to 160 with various construction types (IM B3, IM B35, IM B5). They feature cooling type IC 411 and are equipped with cylindrical roller bearings. The document specifies tolerances for dimensions and mechanical properties, ensuring compatibility with different installation requirements.
Electrical Design: The motors operate at standard voltages and frequencies, with design considerations for efficiency, power factor, and overload capacity. Additional thermal winding protection is included to prevent overheating. The document outlines tolerances for electrical parameters such as efficiency, power factor, and starting current.
Standards and Compliance: The motors meet international standards and are certified by recognized testing authorities. Compliance with ATEX Directive 94/9/EC is ensured, and deviations from standard designs require re-certification.
User Instructions: Guidelines for installation, electrical connection, maintenance, and repair are provided. Protective measures against excessive temperature rise are emphasized, and information on spare parts is included.
Selection Data: Detailed selection data for increased safety motors, including electrical characteristics and dimensions, are provided to assist in choosing the appropriate motor for specific applications.
Motor Ends Definition: According to IEC 34-7, the motor ends are defined as D-end (driving side) and N-end (non-driving side). Motors are supplied with a key fitted, and the second shaft end can transmit full nominal output with coupling service. Power transmission capabilities for belt, chain, or pinion service are available upon request.
Protection Degrees: Defined by DIN VDE 0530 part 5, protection degrees are indicated by 'IP' followed by two numerals. The first numeral indicates protection against dust and foreign particles, while the second numeral indicates protection against water ingress. Specific protection degrees for motor series are available in selection data tables.
Rotation and Bearings: Motors connected to a three-phase mains rotate clockwise as seen from the D-end. Altering rotation direction requires exchanging two terminals. Motors use antifriction bearings with a nominal service life of at least 20,000 hours under maximum load. Sizes 63-160 have life-lubricated bearings. Cylindrical roller bearings support high radial forces, but minimum radial force requirements must be met to avoid damage.
Transport and Vibration: Motors with cylindrical roller bearings can have transport locking to protect against shocks. Vibration intensities are specified in DIN EN 60034-14, with stages N (normal), R (reduced), and S (special) available. All rotors are dynamically balanced, documented on the rating plate.
Noise Characteristics: Noise is measured according to DIN EN 23741/23742, with values specified in dB(A). Noise levels for 60 Hz motors are available on request. Noise data is provided for various motor types and configurations.
Cooling and Ventilation: Motors are equipped with radial fans for cooling, independent of rotation direction. Installation requires maintaining a minimum distance from the fan cover to the wall.
Paint Finish: Normal and special finishes are available, suitable for different climate groups. Standard color is RAL 7031 blue-grey, with special coatings available for thermal, chemical, and radiation stresses.
Design Voltage and Frequency: Motors are supplied for specific design voltages and can operate without changing nominal output within certain voltage deviations. Special voltages and frequencies are available upon request.
Performance and Overload: Motors can handle 1.5 times nominal current for 2 minutes and 1.6 times nominal torque for 15 seconds. Efficiency and power factor are listed in selection data, with partial load values available on request.
Specifications:
The document outlines the specifications for electrical motors, including design voltage, torque, and output. The nominal voltage can deviate by ±5%, and the nominal torque is calculated using the formula M = 9550 x P/n, where P is the nominal output in kW and n is the speed in rpm. The nominal output is specified for continuous operation at a coolant temperature of 40°C and a site altitude of ≤1000 m above sea level. Additional thermal winding protection is provided for monitoring the temperature of the stator winding.

Procedures:
For installation and electric connection, specific regulations must be followed, especially in potentially explosive atmospheres. In Germany, regulations such as DIN VDE 0118 and DIN EN 60079-14 must be observed. Protective measures against excessive temperature rise include using an inverse time-delay circuit breaker with phase-failure protection.

Standards:
The document references several standards, including DIN EN 60034-1 for motor specifications and DIN EN 50014/50019 for increased safety type of protection. Motors are designed for continuous duty and must adhere to specified voltage and frequency ranges to prevent excessive temperature rise.

Recommendations:
Maintenance and repair of explosion-protected machines must comply with specific regulations, and only original spare parts should be used. Thermal machine protection through direct temperature monitoring is permissible if certified.

Motor Selection Data:
The document provides detailed motor selection data, including design points, efficiency, power factor, and other performance metrics for various motor types. The data is presented for three-phase motors with squirrel-cage rotors, specifying increased safety type of protection, insulation class, and degree of protection.
Specifications and Design:
The document outlines various models of electrical machines and their specifications, including types of bearings, wave washers, and seals used in the construction. It details the basic and special designs for heavy bearing arrangements, and provides constructive selection data for terminal boxes and cable diameters.

Product Range:
The company offers a wide range of low-voltage asynchronous machines, including three-phase motors, explosion-protected motors, brake motors, and energy-saving motors. High voltage asynchronous machines and synchronous machines up to 75,000 kW are also available, along with DC motors up to 15,000 kW. The document highlights the availability of complete drive systems and services such as 24-hour support, problem analysis, and maintenance.

Standards and Compliance:
The products comply with relevant standards such as IEC, VDE, DIN, and ISO. Protection degrees range from IP 23 to IP 55 and higher, with options for air or water cooling.

Service and Support:
The company provides extensive service offerings, including on-site problem analysis, project planning, repair and inspection schedules, and operator training. They also offer support for modifications, new installations, and repairs.
