The industrial workhorse: squirrel-cage three-phase asynchronous motors from 0.75 kW to 3,150 kW, 2 to 8 poles; 380/400/460 V at low voltage, 6/10/11 kV at high voltage.
Three-Phase Asynchronous Motor (YE3)
The three-phase asynchronous motor works on the principle of electromagnetic induction and is the most common industrial drive; its simple construction and long service life make it the workhorse of mechanical and electromechanical systems. The MST Motor YE3 series is a general-purpose cast-iron motor in the IE3 efficiency class.
Speed depends on the number of poles: 2 poles 3,000 rpm, 4 poles 1,500 rpm, 6 poles 1,000 rpm, 8 poles 750 rpm. Ten poles and above are built to order.
The table below is an excerpt from the 2-pole (3,000 rpm) series; contact our technical team for the full list and other pole counts.
Values are taken from the manufacturer's current catalogue; ask for a quote for other ratings and pole counts.
- Wide power range — 0.75 – 3,150 kW
- Voltage options — 380 / 400 / 460 V low voltage; 6,000 / 10,000 / 11,000 V high voltage
- Applications — machine building, HVAC, water and wastewater pumps, oil and gas, compressor and fan drives
