3 Tips to Save Energy and Money with Electric Motor

Electric motors are the leading power sources that regulate the speed, performance, and

torque in some of the most important residential, industrial and commercial machines. You can

either search online for the electric motor dealers in Ludhiana or walk into the authorized

dealer shop to find the best quality products. Electric motors may also turn out to be the largest

consumers of electricity and can cause expensive downtime if not maintained appropriately.

Fortunately, you can take the following steps to improve the performance and life of your

electric motor and cut the cost significantly:


1. Soft Start the Motor

The three-phase motors can start in three different ways without the use of VFD:

Hard Start: It is direct-on-line start with a high starting current which may be around 6

to 10 times the rated motor current. During this start, the motor reaches the full speed

instantaneously and may result in belt slippage, wear and tear of the bearings or gears

and possible damage to the other components as well.

Star Delta Start: It uses the contractors and a timer so as to switch between star-

position for starting (utilizing 30% current initially & 25% starting torque) and then

moving to delta for a full load.

Soft Start: In this, the power is gradually applied to the motor and the initial jolt is


Soft starts are the most efficient and the safest of these three aforementioned ways. It protects

the facility from excessive voltage, blown fuses, and compromised electrical flow to other

applications in the warehouse. Soft starters use thyristors, silicon controlled rectifiers and

semiconductors to control the electric current flow and temperature variations as the motor

starts. Thus, it reduces the risk of technical, electrical as well as mechanical failure too.

2. Motor Drive Maintenance

The Variable Frequency Motor Drives, which is popularly referred to as VFD’s, convert the

electrical energy into mechanical energy. It offers controls in order to regulate torque and

speed. In fact, a VFD that functions properly can result in up to 55 percent energy cost savings.

Unfortunately, most people put off the motor drive maintenance till a catastrophic failure is

experienced by the system. The resulting cost of replacement of the complete motor and the

loss of profits due to production downtime during the installation turns out to be more

expensive than the cost of routine repair and maintenance. It is the best to tackle electric

motor drive problems as soon as they arise so that you can avoid costly repair services at the

later stage.

3. Size the Motor Correctly

When operated at a full load, even old motors work highly efficiently. However, as soon as the

load reduces the efficiency of the motor falls away quickly even for the latest high-efficiency

motors. Hence, a high-efficiency motor turns out to be truly efficient when it is used near full

load conditions.

It is a good engineering practice to oversize a motor slightly for a particular application. This

process will not only extend the life of the motor but will also provide extra capacity when it is


needed. In case the motor is oversized, larger than the requirement, it must be re-examined.

You can install energy saving motor controllers in saving energy in oversized motors.

You can find a perfect high-efficiency motor at any shop which deals in motors and water

pumps in Ludhiana. Hopefully, you find the above-mentioned tips useful to improve the life as

well as the performance of your electric motor and save your money at the same time. Do you
