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 :
- 3-PHASE ELECTRICAL MOTORS UPTO 220 KW with Control Panel.
- MOTORISED BLOWERS UPTO 15 KW with Control Panel.
- GEARED MOTORS UPTO 15 KW with Control Panel.
- BRAKE MOTORS UPTO 15 KW with Control Panel.
- DC MOTORS UPTO 90 KW.
- 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 :
- Superior grades of raw materials are being used for the manufacture
of motor for
Navy and special projects (DMDE).
- Higher factors of safety. Thus more rugged motor.
- The no-load current values are lower, power saving even at partial
loads (50 %, 75 %).
- 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.
- 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 :
- The important orders executed / under execution from 1987 onwards
are in
Appendix-I.
- 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.
- 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.
- Shock Calculations for the DOT pump motor (Frame Size – 160)
was approved in
1999.
- 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.
- D.C. Motor developed for DMDE was successfully tested on load
at our premises on
17.02.04 in presence of Comdr. Rank officer.
- 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.
