The single-phase motors MN series are equipped with a C running capacitor placed inside the terminal board box and in series with the starting electric winding.
Overall dimensions are identical to the three-phase motors TN series, except for the dimensions of the terminal board, containing the capacitor, made of impact-resistant plastic.
The capacitor is assembled on to an appropriate support that enables to isolate it from the housing limiting the transmission of temperature and vibrations to the capacitor itself.
The single-phase motors are available with B3, B5 and B14 flange and have following characteristics:
- IEC sizes = 56 ÷ 100
- Nominal power Pn= 0.09 ÷ 2.2 kW
- Polarity = 2, 4, 6
- Energy efficiency= IE1
- Nominal torque Mn= 0.3 ÷ 15.9 Nm
- Rotation speed n = 870 ÷ 2830 rpm
Single-phase motors with aluminium terminal board box are available with ATEX Zone 2/22 - Category 3G/3D Certificate (potentially explosive environments).
All M.T. Motori Elettrici motors are manufactured complying with IEC international standards.
