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 15 to 400 kW. It includes specifications, standards, and design features for these motors, which are suitable for use in potentially explosive environments.
Specifications: The motors are designed with increased safety 'e' protection, conforming to European standards EN 50014/19 and are suitable for hazardous locations where explosive gas/air mixtures may occur. They are available in frame sizes with shaft center heights from 180 to 355 mm and are rated for voltages between 220V and 690V at 50 Hz.
Standards and Regulations: The motors comply with relevant standards such as IEC 34-1, EN 60034-1, and VDE 0530, covering aspects like rating, performance, terminal markings, and starting performance. They also adhere to mechanical standards for dimensions, output ratings, and degrees of protection.
Design Features: The motors feature IP55 protection with external earthing terminals and are designed for direct-on-line starting. They have a stator winding insulated to Class F with a maximum temperature rise of 70 or 90 K at 40°C ambient temperature. The motors are painted in RAL 7031 and include vibration category N compliance.
Explosion Protection: The motors are certified for increased safety 'e' protection, preventing excessive temperatures and sparks. They are suitable for environments with occasional explosive gas mixtures, adhering to regulations such as the Elex V and DIN VDE 0165.
Mechanical and Electrical Design: The document details the mechanical construction, including type of construction, degree of protection, and cooling methods. It also covers electrical aspects like rated voltage, overload capacity, and thermal motor protection using PTC sensors.
Ordering Information: The catalogue provides a 12-position product code for identifying motor specifications, including type, frame size, speed, and special design features. Additional information for special designs is also outlined.
Motor Protection: Increased safety motors require precise disconnection by protective equipment to prevent overheating. According to VDE 0165, motors must be protected against overheating on all phases using current-dependent time-lag devices, such as motor protective switches. These devices must disconnect the motor under short-circuit conditions within the specified time tE. The tripping characteristics should be based on an initial temperature of 20°C, and the breaking capacity must exceed the motor starting current IA.
Phase-Failure Protection: For motors with delta-connected windings, protective relays or tripping devices must be connected in series with the phase windings. If this is not possible, additional protection is required to ensure motor safety in case of phase failure.
Frequency of Starting: Increased-safety motors are suitable for continuous duty and infrequent starts. For challenging starting conditions, motors with different protection types, such as Flameproof "d", should be used.
High-Inertia Starting: This applies when heavy masses need acceleration, causing run-up time to exceed 1.7 times the tE time. Additional starting protection is necessary alongside standard protective devices.
Mechanical Design: Motor construction types are designated according to EN 60034-7 Code I and II. Various configurations are available, such as IM B3, IM B5, and IM V1, each with specific mounting and design features.
Degree of Protection: Motors conform to IP55 protection standards, with options for IP56S and IP65 at extra cost. Installation is suitable for moderate climates, with special finishes available for severe conditions.
Bearings: Standard motors feature lubricators with lithium-saponified grease. Specific bearing arrangements are provided based on motor size and application, with options for reinforced bearings for belt drives.
Belt Drive: Only non-electrostatically charging belts should be used. Calculations for belt tension are provided, considering factors like power, speed, and pulley diameter.
Belt Drive Specifications: Use belts that do not develop an electrostatic charge. The permissible radial shaft load calculation applies to the normal D-end shaft extension of IM B3. The formula for maximum radial shaft load (FR) involves output power (P), speed (n), pulley diameter (D1), and belt tension factor (k). Specific values for k are provided for different belt types.
Permissible Loads: Tables provide permissible radial and axial loads for various motor frame sizes and configurations, both vertical and horizontal. Loads are specified for different speeds (3000, 1500, 1000 min–1) and directions (downward, upward).
Reinforced Bearings: Details on reinforced bearings for special designs are provided, including frame size, type, number of poles, and bearing types for different constructions.
Shaft Extension and Balancing: Motors have a cylindrical shaft extension with a female thread. Additional shaft extensions are available at extra cost. Rotors are dynamically balanced using a half key, with other methods available on request. Vibration categories are specified according to EN 60034, Part 14.
Noise Levels: Motors are designed to have noise levels below the limits specified by EN 60034-9. Noise measurements are conducted according to DIN EN 60034-9, with values provided for different frame sizes and configurations.
Anti-Condensation Heater: Motors can be equipped with an explosion-protected, self-regulating space heater to prevent condensation during standstill. Voltage and heating power specifications are provided.
Electrical Design: Motors are designed for nominal voltages between 220 and 690 V, with a tolerance of ± 5%. Nominal voltage ranges are specified according to DIN IEC 38. Overload capacity allows for operation at 1.5 times the nominal current for 2 minutes without harmful heating.
Specifications: The document outlines the specifications for motors, including their connection, rated output, and overload capabilities. Motors are preferably connected in a star configuration, with special measures required for delta connections. The rated output is applicable for continuous duty at 40°C ambient temperature and altitudes up to 1000 meters. Motors can withstand 1.5 times the rated current for 2 minutes without excessive heating.
Ambient Temperature and Altitude: Adjustments to the rated output are necessary for operations at temperatures other than 40°C or altitudes above 1000 meters. Such modifications require additional certification.
Insulation and Temperature Rise: Motors use Class F insulation according to VDE 0530. Basic motors operate at 40°C with Class B temperature rise. For Class F thermal stresses, rated output can be achieved at higher temperatures or increased output at 40°C.
Thermal Motor Protection: Motor protection must consider operating conditions, using current-dependent switches and overcurrent relays as per VDE 0165. Temperature-dependent thermistors can supplement these protections to prevent excessive winding heating.
Special Designs and Features: The document lists various special designs and features, including different shaft and bearing configurations, flange designs, ventilation options, and electrical specifications. These include increased accuracy, reinforced bearings, and special paintwork.
Order Data: Details required for ordering motors include model type, protection type, output, voltage, frequency, speed, and additional specifications for special operating conditions. Environmental influences and noise level requirements are also considered.
