3 Phase Motors - Available From Power Heating Plants
Our 3 Phase motors all conform to the IEC frame sizing standards. We keep stock of all 3 phase electric motors from 0.75kW up to 18.5kW. These motors are rated for use with Inverters and are suitable for continuous use.
All of our aluminium motors feature sealed for life bearings, meaning that servicing can be kept to a minimum. The fan and cowls are also separate units which can be replaced if damaged, without replacing the entire motor. All Universal Aluminium Motors feature cast feet which can be moved to change the orientation of the terminal box.
Which Electric Motor Do I Need?
What does Poles Mean When Referring To An Electric Motor?
A motors base speed is usually determined by the number of poles it has. The less poles, the higher the maximum speed, with more poles, the speed decreases, but the torque produced by the motor increases. The table below is a nominal guide. Depending on the efficiency of your motor, these will be slightly different (IE2 or IE3).
|Number of Poles In Motor|
|2 Pole||3000rpm (approx)|
|4 Pole||1500rpm (approx)|
|6 Pole||1000rpm (approx)|
|8 Pole||750rpm (approx)|
I Need To Slow My Motor Down To xxxx rpm
If the Output speed you require from your motor doesn't match the ones in the chart this is not a problem. If you use a VSD (Variable Speed Drive) sometimes referred to as an Inverter, you can alter the speed of the motor anywhere between 0 and 100% of its speed to get the exact RPM you require for your fan.
What are the different Motor mounting options?
There are a variety of IEC standard motor mounts available. These are Foot Mounted Motors, Flange Mounted Motors and Face Mounted Motors, all of these can be referred to by a letter and number combination. Have a look at the quick look references below to help:
