1. |
What is Opti power motor? |
| |
Opti-power is a brand name given to
High Performance class of Energy Efficient motors.This is
equivalent to IEEMA Standard Energy Efficient class of
Eff-1 .
|
|
2. |
What are advantages of Opti
power motor as compared to other motors? |
| |
* Energy Saving when
compared to a standard motor of the same capacity.
* Efficiency – Load curve is nearly flat in the
range of 60% to 100% Load.
|
|
3. |
What is
the Pay back period of Opti-Power motors? |
| |
It is approximately 12 months or
lower. It depends upon various factors like motor rating,
motor utilization, load on motor and per unit cost of
electricity.
|
|
4. |
To which
Indian standard does the motor conform? |
| |
Our motors conform to IS 325, 1996.
Special motors that are designed to meet customer’s special
requirements may make it necessary to deviate from certain
clauses of the standard.
|
|
5. |
Why the
circular ribs are provided on your Ring Frame motors? |
| |
The circular design allows dust,
cotton fluffs and other materials to slip off the surface of
the motor body. They easily fall down. Hence, it is a
Self-Cleaning type of design. The cotton fluff, if deposited
on a motor body, can hamper motor cooling and is also a
potential fire hazard.
|
|
6. |
Whether
the motors are suitable for unbalanced supply voltage
operation? |
| |
Yes, as long as the voltage unbalance
is maintained with in the limits specified in IS 325, 1996.
|
|
7. |
Are your
motors suitable for operation through inverters? |
| |
Yes, however this should be specified
while placing the order.
|
|
8. |
Do you
manufacture class H insulated motors? |
| |
We make motors using class F
insulations. We can also make class H insulated motors, if
required, subject to economical order quantity.
|
|
9. |
What is
the overload capacity of your motors? |
| |
The overload capacity is as per IS 325
1996.
|
|
10. |
Can you
offer motors for ambient temperature below 0 deg.-C? |
| |
Yes, motors can be offered for lower
ambient temperature by providing suitable grease.
|
|
11. |
Is there
any built-in protection in your motors? |
| |
Yes, thermistor is provided in each
phase for protection against thermal
Over loads. (except in certain motors of low ratings)
|
|
12. |
Do you under take any
development of special motors? |
| |
Yes, provided the quantity is
economical.
|
|
13. |
What are the types of
lubricants to be used for the motor bearings? |
| |
LCG – 2, SERVO PLEX LC – 2, ALBIDA EP
2. Please also refer the nameplate fixed on the motor for
the greasing instructions.
|
|
14. |
What is the type of paint used
on your motor? |
| |
We are using acrylic paints for our
motors. However, special paints such as Epoxies can be
provided on request at extra price.
|
|
15. |
What is the vibration & Noise
level of your motors? |
| |
They are as per relevant Indian
Standard IS 12075 and IS 12065.
|
|
16. |
What is the maximum
temperature permissible for different classes of Insulation? |
| |
Class B – Insulation 130 Deg. C
Class F – Insulation 150 Deg. C
Class H – Insulation 180 Deg. C
|
|
17. |
What does the term service
factor mean? |
| |
Service factor is defined as the
sustained over load over and above the motor nameplate
rating which will alter the steady state temperature of the
motor.
|
|
18. |
In case of service factor
condition, can the temperature rise limits be increased? |
| |
Yes,
NEMA (National Electrical Manufacture Association, USA)
standard permits 10 Deg. C more than the allowable
temperature rise for the corresponding class of Insulation. |
