SynRM motor and drive packages: the perfect combination

Bogart and Bacall, Bonnie and Clyde, Laurel and Hardy. Some partnerships seem as if they're just made for each other. In the case of ABB SynRM motors and ABB drives, they actually are.

The classic combination of IE5 synchronous reluctance motors (SynRM) and new ABB drives has been designed to maximise your energy savings. So what does it come with?

  • Verified IE5 efficiency (from 1.1 to 350kW, frames 90 to 315))
  • Lower bearing and winding temperatures
  • Longer bearing life
  • Better partial load efficiency
  • More precise process control
  • Permanent magnet motor performance - without rare earth magnets

Taking you to a new level of ultra-premium efficiency it's a pairing which saves you money and energy, reduces your emissions, improves reliability (and so productivity), enhances sustainability and works in all applications.

Why choose a SynRM motor? When you consider that almost half the electricity in the world is converted to motion by electric motors, it makes sense to make this conversion as efficient and as cost-effective as possible...because if every production line was to be just a tiny bit more efficient...imagine the huge amount of energy worldwide which could be saved? Your SynRM motor has to work in conjunction with a drive - that's one of the reasons it's so efficient, but it takes this partnership with the drive to a new level with the drive switching the frequency of the supply current to the motor thousands of times per second.

Reluctant to make the move to 'reluctance' motors? Cautions about your 'induction' to SynRM? Lots of myths abound about what, in fact, is not new technology. It's well established, and it's been around for almost 100 years.

Let's look at some of the misconceptions about SynRMs, because there are lots:

  • It's unreliable because it's new - Ooops, we've already busted that one.
  • It's a more complicated motor, so it'll be difficult to repair - Two things here. It's not that different to an induction motor, in fact with no traditional rotor windings you could argue it was simpler to maintain, and secondly, as it runs cooler than a traditional motor, it actually needs less maintenance. It's a very chilled motor...
  • It's great, but only for specific applications - As long as your application uses a vsd, a SynRM motor is probably the best (and most energy efficient) choice. Constant torque? It's fine. Quadratic torque? Ditto.
  • Well fine, but it's hugely expensive - It's the same price as an IE2 induction motor, but you get the same power from a smaller frame size, or even more power from the same frame...and it's more cost-effective to run. Swapping over the same frame size is ..'simples' as a meerkat might say.
  • You can't get drives to match them - All new ABB drives (and even those from other manufacturers) are now compatible with SynRM motors. If you're buying an ABB SynRM package, the drive and motor won't just be compatible, they'll be perfectly matched to give you optimum efficiency.
  • So you have to buy them as a package - Nope. You have to have a VSD control this type of motor, but they don't have to be bought as a pair..see above. Any drive supplier worth their salt will be able to show you the energy savings you can make using their drive and a SynRM motor.
  • Three words: High torque applications - Well 'extruder' me but three words: Bring it on. It'll perform more quietly, generate less heat and do all of this in a safer fashion than say a PM motor, which can produce high voltages in their terminal boxes if the inverter isn't energising them. Hopefully we 'conveyored' that well enough.

Well, that was quite a list. We were going to provide you with six or so reasons you SHOULD use a SynRM package, but you know what? I think we've covered it.

All you have to do now is email your requirements to and we'll take it from there.

See how you can 'put a ring' on one of the best drive and motor partnerships around.
