Electric motors
Ensuring your electric motors are working efficiently can mean energy savings for your business. Electric motors turn electric energy into mechanical energy. They are in common use for many purposes including pumps, fans and conveyors.
Efficient motors
Noise and heat can indicate energy losses - if you notice eitherof these, investigate the cause.
A variable speed drive can improve efficiency in motors with fluctuating output, throttling or volume control.
You can save energy by:
- Replacing oversized motors with smaller ones - often replacing an old motor with a new one can pay for itself within one year
- Maintaining all drives to the manufacturer's recommendations
- Replacing vee belts with toothed belts, raw edged cog belts or new generation flat belts
- Reducing belt wear with a soft starter or variable speed drive
- Making sure alignment, tension and operation of motors are correct.
Standards
If you're purchasing a new electric motor, check that it meets minimum energy performance standards.
