Three-phase motor DN

two-windingIE14/8 poles

Product description
DN Series motors are three-phase motors offering two selectable speeds via pole-changing connections. They are available in Dahlander/YY single-winding configuration or with double three-phase internal winding for specific pole combinations.

Construction options

• Single three-phase winding in DAHLANDER/YY configuration (single winding) for motors equipped with double polar couples (2/4 and 4/8).
• Double three-phase internal winding for motors with polar couples 2/6, 2/8, 4/6 and 6/8.

Polar couples and rotation speed (rpm)
2/4 — 3000/1500
2/6 — 3000/1000
2/8 — 3000/750
4/6 — 1500/1000
4/8 — 1500/750
6/8 — 1000/750

Available mounting and general characteristics
These motors are available with B3, B5 and B14 flanges and have the following characteristics:

• IEC sizes: 63 ÷ 180
• Nominal power Pn: 0.18/0.12 ÷ 22/18.5 kW
• Energy efficiency class: IE1
• Nominal torque Mn: 0.60/.060 ÷ 99.7/131.4 Nm

Additional information
On specific customer request M.T. Motori Elettrici can supply triple-speed motors, supported by its technical department. All M.T. Motori Elettrici motors are manufactured in compliance with IEC international standards.
