THREE PHASE SQUIRREL CAGE ASYNCHRONOUS MOTORS

ELK Motor has been founded by major shareholders of Yılmaz Reduktor, as a continuation of the product family. ELK Motor manufactures electric motors from 71 up to 280 frame size in a 40.000m2 closed area built on a 100.000 m2 open area. All motor series are designed and manufactured in accordance with European standards and in IE2 and IE3 efficiency classes. The main design and technology of ELK Motor is completely suitable to the IE3 efficiency class. Since the outside dimensions of the IE3 and IE2 design are completely same, the replacement of the IE2 motor with IE3 motors will be done easily....

TECHNICAL INFORMATION

IEC / EN / UL Compatibility All of standard ELK Motors are designed, manufactured and tested according to the IEC and EN standards given below. IEC 60034-1 Rating and performance IEC 60034-2-1 Methods for determining losses and efficiency IEC 60034-5 Classification of degrees of protection IEC 60034-7 Symbols of construction and mounting arrangements IEC 60034-8 Terminal markings and direction of rotation IEC 60034-11 Built-in thermal protection IEC 60034-18-1 Functional evaluation of insulation system IEC 60034-30 Efficiency classes (IE Code) EN 50347 Dimensions and output for electrical machines...

Mechanical Construction 71-160 frame size ELK Motors provides flexibility for different mounting types through their detachable feet which can be mounted on three sides. This feature allows terminal box assembly on the desired side. Terminal box is on the top for standard motors. 180-280 frame size motors have fixed feet construction. MOTOR SIZE 180-280 Additionally the housing and end shields are designed symmetrically for all the frame sizes, so that the drive and non-drive side end shields can be replaced and the direction of the rotor shaft group can be changed. By making this end shields...

Electrical Construction Standard ELK Motors have insulation Class F while the temperature rise is Class B. This means the motors will have a longer service life and work under hard conditions. Upon the customer's request, Class H insulation motors are manufactured. The motors shall be connected in star or delta according to rated voltage given in their nameplate and the network voltage that they will be connected. For phase to phase 400V supply the motors with 230/400V nameplate values shall be connected in star and the motors with 400/690V nameplates values shall be connected in delta. Y Star...

Motors With Variable Speed Drives Standard ELK Motors are suitable for variable speed drives. The frequency range that the motor can be driven with their fan is given below with blue line. If the motor will be driven in a wider range then a separately driven fan is necessary. By using a separately driven fan, the motors can be driven in the range defined by red line. Motors In Several Environmental Conditions ELK Motors are designed to operate at ambient temperature up to 40°C according to IEC 60034-1. Rated output will change at the % ratings given below for different ambient temperatures.

Winding Insulation / Temperature Rise Classes INSULATION CLASS All standard motors in the ELK Motor range have F (155 ° C) class electrical insulation system. However, by means of its superior design features, the temperature rise of all standard motors remain within the Class B temperature rise limits when operating under rated conditions. Depending on the safety margin of the temperature rise class provided, our motors can provide 15% higher rated output power with a service factor of 1.15 (SF). Maximum Winding Temperature Limits of Winding Temperature Ambient Temperature B Class B insulation...

Construction Types ELK Motors are manufactured according to International Mounting Standard IEC 60034-7. Mounting codes and diagrams according to IEC 60034-7 Horizontal Mounting Codes Vertical Mounting Codes

Standard ELK Motors are equipped with ball bearings with ZZ shields as listed below, according to frame size. NU-NJ bearings are optional.

Radial Loads Radial Load [Fr]: Radial load can be calculated according to below written formulae. Calculated radial load must be below permissible radial loads given at tables. If above, please contact with us. F« = k 'D^r10,(iV) Correction of Permissible Radial Load If the radial load is applied between points x0 and xma x , the permissible radial load can be corrected with the following formulae.
