3 Introduction Electrical drives in their many variations are now in use in every branch of industry. In most processes, they determine by virtue of their characteristics the economy of production. The threephase asynchronous motors for low voltage from VEM motors GmbH meet the needs of operators with the regard to allround versatility, superior performance parameters, environmental compatibility and high standard of reliability. VEM motors are designed for the whole European market and offer economical performance due to high motor efficiencies versatility and reduction of stock due to series version in IP 55 degree of protection (higher degrees of protection up to IP 66 on request) optional terminal box position right /on the top / left increased lifetime, reliability and thermal overload capacity by series version insulation class F with thermal reserve (special version insulation class H on request) environmental acceptability due to use of a low-noise and bi-directional ventilation system supply option complying with Eastern European standards performance option of a classic IEC/DIN series and on request a progressive one based on the IEC 72 for attachment dimensions and frame sizes attachment options for components as impulse sensors, tacho generators, brakes, speed sensors and forced-ventilation units for accomplishment with recent control methods 3

5 Efficiency The General Directorate Energy of the Europeam Commission and CEMEP as an association of the European motor and drive manufacturers have, in a Voluntary Agreement, settled to classify three-phase low voltage asynchronous motors according to their efficiency. The Agreement includes all two-pole and four-pole standard motors in the output range between 1 and 100 kw, and the classification is done by labelling the motors with one of the three classes eff1, eff2, eff3, where eff3 is attached to motors with nowadays usual efficiencies, eff2 belongs to motors with significantly increased efficiencies, and eff1 is a mark for high-efficiency motors. In the Agreement is specified, to mark the motors on the nameplate with the respective lass and to declare the respective classes for the motors in technical catalogues, moreover, in the catalogues must be specified data about efficiencies at partial loads. In the Agreement the DIN EN is expressly specified as the test procedure for determination of loss and efficiency. The mark for the efficiency classes is a Registered Trademark. VEM is among the subscribers of this Voluntary Agreement. For the North American market, with respect to efficiency of three-phase low voltage motors the legal provisions of the socalled EPAct (or EPCA = Energy Policy and Conservation Act) are in force, by them, depending on the pole-number, are also minimum efficiencies determined (Table of NEMA MG1 or Tables 2 and 3 of CSA C390). The output range of the affected motors is between 1 and 500 hp in NEMA MG1, and between 1 and 200 hp in CSA C 390. When classifying European motors according to the American rules, attention must be paid to the fact that the test procedure for determination of loss and efficiency is expressly specified with the Standard IEEE 112, and that, when using this procedure for determination of efficiencies, the results will have significant deviations from those of DIN EN , i.e. it results in considerably lower efficiencies. Motors of the VEM series WE1R are certified by CSA according to CSA C390. Bearings / Bearing lubrication VEM motors are equipped with bearings from excellent manufacturers. The bearings have a nominal service life of at least 20,000 hours for maximum permissible load conditions. Without additional axial loading for coupling service the nominal bearing service life is 40,000 hours. The versions - fixed bearing N-end - without fixed bearing - permanent lubrication - relubrication device - heavy bearing arrangement D-end (for increased lateral forces) - easy bearing arrangement and the - bearing schedules - disc spring and wave washer schedule - V-rings - figures of bearing arrangements - flat grease nipples Any grooved ball bearings have disc springs and wave washers, respectively, thus they are preloaded. This is not true for versions with cylindrical roller bearings. The version "fixed bearing N-end" is possible for motors "without fixed bearing". Motors with permanent lubrication are also available with a degree of protection IP 56. Motor sizes are fitted with life-lubricated bearings. For motors from size 180, depending on the useful life of grease, bearings must be regreased in good time so that the scheduled bearing service life is reached. Under normal operating conditions, the grease packing will last for 10,000 hours of operation with 2pole version and for 20,000 hours of operation with versions from 4poles upwards without being renewed. For motors fitted with relubrication device and working under normal operating conditions, the grease will last for 2,000 hours of operation with 2pole version and 4,000 hours of operation with 4- and mor-pole versions. The standard grease is a KE2R-40 type acc. to DIN are shown in the bearing arrangement tables. Fixed bearing D-end possible on request. Use of cylindrical roller bearings Using cylindrical roller bearings (heavy bearing arrangement), relatively high radial forces or masses can be accepted at the motor shaft end, e. g. belt drives, pinions or heavy-duty couplings. The minimum radial force at the shaft end must be at least a quarter of the permissible one. Account must be taken of permissible shaft end loading. Both these values are found in the diagrams. Important Note: Radial forces below the minimum value can lead to bearing damage within a few hours. Test runs in no-load state are only permissible for a short period. If the special minimum radial force cannot be met, we recommend the use of grooved ball bearings (easy bearing arrangement). Bearing change on request. 5

6 Vibration behaviour The permissible vibration intensities of electric motors are specified in DIN EN The vibration intensity stage N (normal) is achieved or bettered by VEM motors in the basic version. The vibration intensity stages R (reduced) and S (special) are available at extra carge and depending on the type. Please consult the manufacturer. According DIN EN the following intensities are recommended: Vibration intensity Speed range Limit values of vibration velocity (mm/s) stages rpm in frequency range 10 to 1000 Hz for sizes N (normal) R (reduced) above S (special) above All rotors are dynamically balanced with the half key inserted. This balancing is documented on rating plate with the letter H behind the motor number, balancing with full key on request. In that case, the code letter behind the motor number will be F. Noise behaviour Noise measurement is carried out according to DIN EN 23741/ at design output, design voltage and design frequency. In accordance with DIN EN , the spatial mean value of the measurement area sound pressure level LpA measured at a distance of 1 m from the machine outline is stated as noise intensity in db (A). The A-sound power level L WA across the measurement area dimension L S (d = 1 m) is also quoted with L WA = L pa + L S (db) The measurement area dimensions are independent from the machine geometry and are for L S (db) size The tabular value +4 db (A) applies as an approximate value for motors in 60 Hz version. Binding data for 60 Hz are available on request. The noise value for the basic types are quoted in tabular form. For special versions please refer to the manufacturer. Ambient temperature All VEM motors in the basic version can be used at ambient temperatures from -35 C up to +40 C. Overload capacity In compliance with DIN EN , all motors can be exposed to the following overload conditions: times the rated current for 2 min times the rated torque for 15 s (1.5 times for I A /I N < 4.5) Both conditions apply to design voltage and design frequency. Motor protection The following motor protection versions are available as an option: - motor protection with PTC thermistor sensors in the stator winding - bimetallic temperature sensor as NC contact or NO contact in the stator winding - resistance thermometer for monitoring the winding or bearing temperature on request 6

7 Tolerances Electrical parameters As specified by DIN EN /02.99 the following tolerances are permissible: Efficiency (indirect calculation) (1-η) at P N 50 kw (1-η) at P N > 50 kw Power factor 1-cosϕ min max Slip ± 20 % P N 1 kw (at rated load and operating temperature) ± 30 % P N <1 kw Starting current + 20 % (in the planned starting circuit) no restriction downwards Starting torque -15 % and + 25 % Pull-up torque - 15 % Pull-out torque -10 % (with the application of this tolerance M K /M at least 1.6) Moment of inertia ±10 % Noise level (sound pressure level) +3 db (A) These tolerances are permissible for the values assured for three-phase asynchronous motors, taking the necessary manufacturing tolerances and materials variations of the raw materials used into account. The standard contains the following notes on this: 1.A guarantee for all or any of the values shown in the table is not mandatory. In tender the guaranteed value for which permissible deviations should apply must be expressly specified. The permissible variations must correspond to those stated in the table. 2."Guarantee": In some countries, a distinction is drawn between guaranteed values and typical or declared values. 3.If a permissible deviation only applies in one direction, then the value in the other direction is not limited.
