| 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 Vs 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.
|
| 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 temp. permissible for different classes of Insulations? |
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 temp 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.
