Technical notes Mounting types The following diagrams show the most common mounting types according to DIN EN 60034-7, Code I. The variable components of the different mounting types are shwon in orange.

Technical notes Voltages and frequencies The tolerances of the voltages and frequencies of the mains network are regulated by the EN 60034-1 standard. In range A, a combination of a voltage deviation of +/-5% and a frequency deviation of +/-2% is permissible. In the extended voltage range B, a combination of voltage deviation of +/-10% and a frequency deviation of +3% / -5% is permissible. Electrical tolerances according to DIN EN 60034-1 Power factor at least 0.02 not more than 0.07 ±20% Starting current in starting circuit +20% with no downward limit Starting torque Pull-up torque...

Technical notes Mechanical balancing All rotors are dynamically balanced according to DIN EN 60034-14 with half feather key according to vibration severity level A (normal). In accordance with DIN ISO 8821, the balancing type "half-key balancing" is prescribed. The motors are painted in RAL 7030 as standard. The coating of the motors corresponds to C2 "medium" according to DIN EN ISO 12944. The coating and color can be adapted on request. Operating modes The rated power is always stated for "S1, Continuous Duty" according to DIN EN 60034-1. If short-time duty (S2) or intermittent duty (S3,...

Technical notes Protection class All motors are designed as standard with IP55 level of protection according to DIN EN 60529. If required, the level of protection can be increased to IP66. (IP = International Protection) The abbreviation IP is followed by two digits: The first digit indicates the level of protection that the enclosure provides against the ingress of solid foreign objects. The second digit indicates the level of protection that the enclosure provides against the ingress of water. Brief description of the level of protection: First digit Second digit 5 = Water jets 6 =...

Technical notes Bearings The nominal bearing life (Lhio) is at least 20,000 hours if the loads given in the following table apply. Up to frame size 280 the motors are equipped with closed bearings as standard. From frame size 315 open bearings with relubrication devices are fitted. The values given in the following table apply to operation at 50 Hz. If the motor is operated at 60 Hz, the values must be reduced by 10%. Starting from frame size 280 we recommend the use of an insulated bearing on the non-drive side of three-phase motors. Frame size

Technical notes Motor protection Various protective devices are available to prevent damage to the motor due to overloading. The following shows which protective component can be used for which type of protection. Winding protection Bearing protection PTC – definition A PTC thermistor is a temperature-dependent component that emits a signal. The motor current is interrupted via a tripping unit connected to the PTC thermistor. If the measured temperature reaches a certain limit value, the resistance of the PTC increases rapidly and the tripping unit switches off the motor. PTO – definition A...

Technical notes Wiring diagram for three-phase motors The following wiring diagrams show the wiring from the winding to the terminal board. This type of wiring is intended for direct mains connection and direct start-up. For star-delta operation, the jumpers must be removed and the motor must then be controlled via an external circuit. Certificates UL listed motors Frame sizes 80-355 Number of poles: 2–6 File-Nr.: E480221 Electric design according to NEMA Explosion-proof motors Zone 2 Zone 22 Flameproof enclosure CE marking Products comply with EU directives China Compulsory Certification...
