Indian Navy and Coast Guards have been using ours motors from 1987 to date. We are Defence Approved Unit registered with DQA (WP). Our Registration No. SS-DP-GDE-II-0500(P) Dt. 03/05/2006, valid upto 02/05/09.

We are registered for the following items :

  1. 3-PHASE ELECTRICAL MOTORS UPTO 220 KW with Control Panel.
  2. MOTORISED BLOWERS UPTO 15 KW with Control Panel.
  3. GEARED MOTORS UPTO 15 KW with Control Panel.
  4. BRAKE MOTORS UPTO 15 KW with Control Panel.
  5. DC MOTORS UPTO 90 KW.
  6. FABRICATION OF COUPLING OF PRIME MOVER
    ALTERNATOR UPTO 400 KVA
     

For DMDE, the special Naval Project, we have cleared 60 Nos. motors upto March-04. This involved five motors types – 7.5 kW, 2.2 kW, 1.1 kW, 0.55 kW – and 0.25 kW. We have complied with the respective QAPs in toto. No deviation in any of the parameters was requested by us. Also no deviations were observed by DQA as well as DMDE. Fabricated M. S. Stator housing with light weight were manufactured. The motors 2.2 kW, 1.1 kW, 0.55 kW and 0.25 kW were shock tested at NPOL, Kochi and where passed during these testing. The savings in weight were from 1.5 % to 15 % from the imported (Russian) motors having Aluminium housing. All performance parameters, as specified for Russian motors have been achieved or surpassed in our motors.

GRSE : We have manufactured motors for Diesel Oil transfer Pump – a very slow speed motor. Syn. RPM – 500, with 18 % saving in weight compared to previous vendor. We also achieved superior values of efficiency. Thus the motor will draw lesser electrical energy during its entire useful life.

Development of Kasara Gate Winch Motor for MDL Import Substitute : M/s. Mazagon Dock Limited had placed onto us the order for 1 No. double speed Motor in 250 M Frame size (Orginal : Crompton Parkinson, U.K. Make)

This motor drives the Kasara Gate at Mazagon Dock Limited. It has a provision that, if while pulling the rope, the motor can be run in the reverse direction at a considerably slow speed to correct the slack. This requires two windings of 1500 RPM and 500 RPM.

We had successfully manufactured this motor with considerably superior in electrical performance and without any deviation in mechanical values.

No other Indian manufacturer was coming forward to offer equivalent motor of such a critical nature.

Energy-Efficient Motors for Refits : We have manufactured 1 No. – 25 HP and 1 No. – 12.5 HP motors for Refits for Cochin Ship Yard Ltd, in March-04 and April – 04.

Both motors were Energy Efficient motors having no-load current values as 9.3 A and 6.1 A. resp. Our motors will result in the savings of electrical energy, even at partial load conditions. Also they will have superior values of power factor. This will result into lesser power (kW) as well as lesser KVA load on the ship supply.

Superior performance values for Defence, can be achieved with continous improvements in the Technology-Design of Products. They are :

  1. Superior grades of raw materials are being used for the manufacture of motor for
    Navy and special projects (DMDE).
  2. Higher factors of safety. Thus more rugged motor.
  3. The no-load current values are lower, power saving even at partial loads (50 %, 75 %).
  4. The noise level of our motors are well within specified declared limits. This can be achieved by the fabrication of special designed fan.
    Noise Level : Navy is concerned about the Noise Level of motors. With verbal discussion with
    Ministry of Defence, we have done extensive Designing and Testing for controlling
    this parameter. The results are encouraging.
  5. The vibration value achieved in our motors is from 0.006 mm to 0.010 mm in 7.5 kW, 2 Pole motors developed for DMDE. Such precision grade values can be achieved in motors for defence by implementation of techniques same as motors for machine tools.

Some of the outstanding achievements for Defence are as follows :

  1. The important orders executed / under execution from 1987 onwards are in
    Appendix-I.
  2. Frame sizes 80 and 132 were shock tested successfully at CQAE, Bangalore in 1999.
    These motors were for DMDE.
    A) M/s. Walchandnagar Ind. Ltd.
    B) M/s. Triveni Engineering and Ind. Ltd.
  3. Frame sizes 71, 80, 90 and 100 were shock tested successfully at NPOL, Kochi in
    Oct. 2002.
    These motors were for DMDE – Air Handling units and Air Handling
    Equipments.
    A) M/s. Moosa Haji Patrawala Pvt. Ltd.
  4. Shock Calculations for the DOT pump motor (Frame Size – 160) was approved in
    1999.
  5. IP-55 Testing was conducted successfully on our motors :
    A) At CIL, Bangalore – on 03.03.1987
    B) At our works, in presence of QAE (WE) on 13.02.04.
  6. D.C. Motor developed for DMDE was successfully tested on load at our premises on
    17.02.04 in presence of Comdr. Rank officer.
  7. We are also Registered with Mazagon Dock Ltd., Mumbai.
    Registration Number AGM (M) / KJM / MI / REGN / ELEC / MOTOR / 388 / 02 Dtd. 29.11.02.
    Renewed and amended on 27.02.04, valid upto 2005.
