ELK Motor has been founded by major shareholders of Yılmaz Reduktor, as a continuation of the product family. ELK Motor manufactures electric motors from 63 up to 315 frame size in a 50.000m² closed area built on a 135.000 m² open area. All motor series are designed and manufactured in accordance with European standards and in IE2, IE3 and IE4 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...

IEC / EN / UL Compatibility All of standard ELK Motors are designed, manufactured and tested according to the IEC and EN standards given below. Methods for determining losses and efficiency Classification of degrees of protection Symbols of construction and mounting arrangements Terminal markings and direction of rotation Noise limits Built-in thermal protection Vibration limits Functional evaluation of insulation system Efficiency classes (IE Code) Standard voltages Dimensions and output for electrical machines Electromagnetic compatibility Rotating Electrical Machines - General Requirements...

Mechanical Construction 63-180 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. 200-315 frame size motors have fixed feet construction. 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 and rotor shaft group...

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. Electrical Connections Cable Gland and Blind Cap Frame Size Cable Glands Blind Cap Terminal Connections Frame Size Terminal Size 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...

Motors at 60Hz Network Standard ELK Motors that have been manufactured for 50 Hz power supply can be used at 60Hz network. The ratios given below indicate changes in the given rated values. 50 Hz Rated Voltage 230V 400V 400V Rated Speed Rated Torque Rated Current Break Down Torque Starting Torque Rated Power Motors With Variable Speed Drives Standard ELK Motors are suitable for variable speed drives. The frequency range that the motor can be driven wit 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...

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 Class B insulation...

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

Radial Loads Radial Load (FR): Radial load can be calculated according to below written formula. Calculated radial load must be below permissible radial loads given at tables. If above, please contact with us. Correction of Permissible Radial Load If the radial load is applied between points x0 and xmax, the permissible radial load can be corrected with the following formula. P: Motor Power (kW) D: Pulley Diameter (mm) n: Motor speed (rpm) k: Radial load factor • Spur Gears, chain drives with low speed = 2,1 • Trigger Belts = 2,5 • V type belts = 5 FR

Radial Loads HORIZONTAL MOUNTING - Permissible Radial Loads Mounting Positions IM: B3, B5, B6, B7, B8, B14, B34, B35 Fa = 0 Frame Size Fa0 : Permissible axial load Fr : Radial load : Permissible radial load at shaft spigot.
