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.
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
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.
Our mission is based on social responsibility and sustainable development. We are aware that living in a healthy natural environment is our wealth, which we want to preserve through sustainable operations for our employees, who return to the company's location every day, as well as for the wider local environment. A clean and healthy environment is a real treasure, but it is also becoming increasingly rare.
In about a year we will be cruising the streets on “Dreem” electric kick scooters, which will be powered by innovative Domel in-wheel motors with permanent magnets. And when riding them, we will be using impact-absorbing smart helmets.
