Lawkim motors are a class apartHigh qualityCompetitive pricesHighly reliableManufactured in a world class plant
RangeLawkim has a wide range of motors ranging from 20 watts (0.025 hp) to 2250 watts (3 hp) in single phase designs and in three phase designs for 50 & 60 Hz. Lawkim takes keen interest and pride in developing special motors for customers, should standard motor range not suffice.
StandardsFrames B42, B48 & B56 conform to BS 2048 part 1 for dimensions and BS 5000 part 11 / IS 996 for performance. 100s frame motors conform to IS 996 for dimensions and BS 5000 part 11 / IS 996 for performance.
RatingAll standard motors are continuously rated to comply with performance standards. Special motors for cyclic or short time duties can also be offered against specific applications.
Lawkim offer following enclosuresDrip proof (DP)Totally enclosed (TE)Totally enclosed fan cooled (TEFC)Air over motors (AOM)
Various types of mountings are availableFootStator padFlangeFoot cum flangeEndshield padStudSpecial mounting if required
Bearing & LubricationSleeve bearing motors are lubricated for life by using Permawick lubrication system. This can give 50, 000 hours of operation without lubrication at normal running. Ball bearing motors use double shielded deep groove bearings and are life lubricated. This offers you trouble free motor life.
Centrifugal gear and Open circuit switchField proven centrifugal gear is used for trouble free operation. Open circuiting switch has sintered contact/s consisting of silver alloy and copper. These contacts have excellent anti-weld properties and can safely rupture heavy current.
Rotor / ShaftsAll shafts are made of EN8 steel and ground to 10 micron accuracy. All shafts are given anti rust treatment. Stainless steel shafts can also be supplied if asked for.
Application EngineeringWith special emphasis on customer satisfaction, Lawkim can develop a motor as per customer's application requirement
Rotomotive asynchronous three phase Delphi series motors are built with dimensional conformance to Indian Standard IS:1231, IS:2223 & International standard IEC 71-1.

Improved Efficiency - Type - ME 0.12kW - 90kW, Frame -63-280MHigh Type - Type MI 0.37kW-315kW, Frame 71-355LMotors are also offered in multi speed and non standard outputs / voltages / frequencies. These motors can be used in Zone 2 areas as per IS 5572 / IEC 60079-7:2001
Salient features of TEFC Standard Motors :Terminals and Connection :External connections of client's power cable to the motor terminals in terminal box must be rigidly gripped and secured against loosening and twisting. This is achieved with the help of a specially designed Terminal Plate provided in the Terminal Box.
Terminal Box :The motors in frame size 63 to 80, 180, 250 to -355 are provided with terminal box on top. Side T Box can be provided on request in frame sizes 180 and above. The terminal box for frame size 90S to 160L is fitted on the right hand side, seen from the driving end. Terminal box on left-hand side can also be provided in frame size 90S to 160Lon request. An earthing terminal is provided in the Terminal Box.Terminal Boxes in frame sizes 63 to 355L can be rotated through 360 in steps to 90 to suit the cable location.
Air-gap :Radial air-gap of the motors is such that the minimum air gap values specified in IS: 6381 are fully satisfied
Enclosure :AIncreased Safety Motors have a degree of protection IP55 in accordance with IS: 4691 as a standard feature. In addition, all flange motors (B5 and B14) have Oil Tight Shaft (OTS) protection. Motors with V1, V5 and V18 mountings are provided with a canopy fitted on the top of the fan cowl
Winding and Rotor Cage :The stator winding and rotor cage are so designed that the limiting temperature specified in IS: 6381 are not exceeded even at the end of time tE.
Name Plate :Stainless steel name plate is provided with each motor. Over and above the normal name plate details, other data such as time tE, starting current, temperature-Class, type of protection, approval certification etc. are also provided.
Paint :Acid Alkali Proof epoxy paint is provided on all motors.
Certification :ME motors are approved by PESO, Nagpur. A declaration to this effect is incorporated on the name plate.
