Energy Optimising

With rising energy costs, products offering energy savings are becoming increasingly important in helping businesses reduce their energy usage.

The vast majority of electric motors in use today are fixed speed, fixed voltage AC induction motors. These motors consume two thirds of the total electricity used in industry. With this in mind, using a technology that could save energy on fixed speed induction motors should be a consideration when replacing motor starters or designing new systems.

Using a patented Energy Optimising system within many of the Soft Starters the technology could save up to 40% of the energy consumed by a lightly loaded motor.

How it works
The energy optimising system works by reducing the current and iron losses of a motor not running at full load. The energy savings will depend on a number of factors including the efficiency of the motor and the load.

Our soft starters will also save businesses money by reducing the electrical and mechanical strain placed on applications – resulting in less ‘down time’ and maintenance cost on electrical circuits, gearboxes, belts and associated mechanical components.

An example of the energy savings that could be made using the energy optimising system is shown below :

20kW Motor Running at 20% Load




This diagram shows a 20kW motor that is running at 20% of its full load capacity. The application is calculated to be losing 0.6kW per hour through the heat generated in the motor windings, plus an additional 2.6 KW per hour through iron losses in the motor. The total efficiency of the application is shown as 54%

Saving 1.8kWh every hour while on part load!

This example shows how the Fairford energy optimising system reduces the energy consumed. Once the optimising process takes place, the heat generated is reduced to 0.4kW per hour and the iron losses of the motor reduced to 1 kW per hour. The total efficiency of the application is shown as 71%.

In this example, the optimising system would produce a saving of 1.8 kW per hour.

The annual savings amount that could be achieved for a 1.8 kW per hour reduction is shown in this table.

The price of electricity is calculated using a value of £0.13 per kWh




The above is a worked example; every application is different and will generate different levels of savings.

ENERGY OPTIMISING FOR FIXEDSPEED INDUCTION MOTORS.

It is well known that an induction motor connected to the normal fixed-voltage supply network will experience a worsening power-factor and efficiency as the motor load reduces.
This effect is due to the rotor current vector shortening and swinging towards a more upright angle while the rotor speeds up and approaches synchronous speed under the influence of excess flux.
Because the motor terminal voltage remains fixed to that of the power supply, the magnetising current remains constant and the resultant stator current vector shortens and falls back towards the magnetising current vector. As a consequence, the phase angle (?) between the supply voltage and the stator current vectors increases, and the cosine of the phase angle (known as the power-factor) tends towards zero. In addition, because the mechanical and magnetising losses remain constant although the load (mechanical output) is falling, the motor efficiency also tends towards zero.
