High Performance and Ultra-High Efficiency Motors for Industrial Fans
Domel’s permanent magnet synchronous (PMS) motors are developed to offer and guarantee ultra-high performance at the IE5 efficiency level (and above), and a maintenance-free long lifetime.
Domel motor types NZA and ZZ are suitable to drive industrial fans.
Key features:
- 750W up to 55 kW (from 2 Nm to 180 Nm)
- speed up to 6,000 rpm
- efficiency level above IE5
- the motor is highly efficient over the whole operating range
- use of ferrite magnets
- top quality
- long lifetime
- very robust due to the high level of protection
With Ultra-High Efficiency to Reduce the Total Ownership Cost
Asynchronous motors are mostly used to drive industrial fans, especially at powers above 6 kW. The market is not so effectively covered by PMS and reluctance motors, as these require a higher initial investment. However, PMS motors have up to 40% less losses compared to the equivalent IE3 asynchronous motors due to the secondary magnetic field being generated from the permanent magnets rather than copper windings. At partial load the difference in efficiency is even higher.
Energy costs through the life cycle represent the majority of the overall operating costs. If operating costs can be reduced, profitability is increased. PMS motors guarantee high energy savings and hence reduced payback time due to much higher efficiencies compared to asynchronous motors. As an additional bonus, system also becomes more environmentally friendly.
Innovative motor construction
Domel has developed state-of-the-art motor construction, which offers the highest efficiency in small size and lightweight motors with the use of non-rare earth, ferrite magnets.
The unique electrical design enables us to offer motors with high operating speeds, up to 6,000 rpm. When increasing the speed of the motor, the difference in size and weight between asynchronous and PMS motors also increases significantly, in favour of the PMS motors.
To meet an application’s specific requirements for pressure, flow, volume, etc., variable frequency drives are often required. The majority of these drives are also capable of running PMS motors. There is thus no need to adjust the electrical part of system when using PMS motors.
More Domel insights:
Let’s take a closer look at why the e-bike is so amazing. It contributes to sustainable mobility and also helps improve the health of individuals and of society as a whole. The option of purchasing a Domel-driven e-bike bearing your company’s logo provides an additional incentive for increasing physical activity. Did you know that we offer personalised bikes? Riding an e-bike can help employees improve their physical fitness, reduce their stress levels and help them on their way towards a healthier lifestyle. They can now incorporate physical exercise into their daily routine, which eliminates the need to spend time at the gym. But that’s not all the e-bike has to offer. Adaptable mobility is another one of its many super powers, helping employees avoid traffic jams and providing them with a fast and efficient means of getting around. E-bikes are perfect for shorter or medium-length distances, and can be combined with public transport for the best results. And let’s not forget about how much money they can save on fuel and parking charges. E-bikes can open the door to mobility and independence for every employee, not all of whom will have a driving licence or a car. Let’s take a look at how e-bikes are saving the planet. Their CO2 emissions are low because they don’t produce direct exhaust gases or particles. This improves air quality. Domel encourages its employees to adopt a healthy and active lifestyle in their free time. It places great emphasis on recreation, to which it gives substantial financial support. We help finance recreational activities away from the workplace, including skiing, swimming and group recreation in sports halls. We also co-finance massages, visits to the sauna, and holiday accommodation by the sea and at spa resorts. We cover the registration fee in full for employees who wish to take part in running and cycling events, subsidise season tickets for the swimming pool, sauna and tennis facilities at Ratitovec institute, and provide vouchers for group exercise, fitness, massage and recreational swimming in Železniki, Škofja Loka and Kranj. During the summer months, we exercise and take part in various events at Selca sports park. Every year we organise an unforgettable employee picnic, which provides a perfect mix of entertainment and sport. In the autumn and winter we organise group recreation, where employees can play badminton, table tennis, five-a-side football, volleyball or basketball for free. There can be no excuse for not taking part in fitness or group activities on grounds of price, as we provide vouchers that keep costs to a minimum. And if you’re a skiing enthusiast, you’ve come to the right place, with low-price ski passes available for the Soriška Planina, Stari Vrh, and Cerkno ski resorts. Every day we make a wide range of apples available for our employees. We do all of this to promote sustainability and our employees’ health. E-bikes are proving to be a key factor in the development of a more sustainable future. Not only do they reduce CO2 emissions, but they also provide long-term benefits for individuals and the environment. The combination of fun, recreation and e-bikes gives our employees an unforgettable experience. We are building a more sustainable future – one that connects us and makes us healthier, happier and full of energy.
