3 phase (230V/400V) 2-pole (3000 1/MIN) electric motors
Description
The three-phase, 2-pole electric motors have a theoretical speed of 3000 1/min at 400V operating voltage and 50Hz. The real speed is somewhere around 90% of the theoretical speed. Always check the speed of the electric motor you want to purchase.
The 3-phase two-pole electric motors available in our webshop can be purchased with different flange designs. B3 stands for rimless footed version, B14 stands for small-rimmed baseless version, B5 stands for large-rimmed baseless. The B34 is the electric motor with small flanges and bases, the B35 is the electric motor with large flanges and bases. Our stock usually includes B34 engines.
Attention: When using our electric motors, either a motor protection switch or a frequency converter must be used for their intended purpose. Engine burnout is improper use, it does not entitle you to warranty repair!
What does 3 phase motor mean?
3-phase electric motors include three windings. Under operating conditions, a rotating magnetic field is created that moves the rotor. The speed of the magnetic field is different from the speed of rotation of the rotor, so they are also called asynchronous motors. Because of its principle of operation, it is also called an induction motor. Asynchronous induction motors draw a lot of current when starting and have less torque when starting. Therefore, these engines were previously started using a star-delta switch. The switch changed the electrical wiring of the motor. Nowadays, we use electronic devices, usually a frequency converter, when starting the electric motor.
Attention! Energy efficiency class IE refers to motor efficiency. 1 is the base, 2 is better, 3 is good, 4 is best. According to Regulation (EU) 2019/1781, IE4 motors may be put into operation in continuous operation (Duty S1) or partial operation (Duty S3>=80 Duty S6>=80) up to power up to 0.12-0.749 kW at least IE2, 0.75-1000kW at least IE3, power between 0.75 and 200kW, IE4 motors in case of 2-4-6 poles after 01.07.2023.
