Asynchronous motor TN

three-phaseIP55ATEX

Overview
Series of standard IEC motors with three-phase power supply, cl. F insulation and IP 55 protection class (on request IP56, IP65, IP66). Characterised by a high degree of reliability, they can be used in countless application solutions.

Construction and mounting
The three-phase motors are available with B3, B5 and B14 flange.

Main features

• IEC sizes = 55 ÷ 200
• Nominal power Pn = 0.05 ÷ 37 kW
• Polarity = 2, 4, 6, 8 • Energy efficiency = IE1, IE2, IE3
• Nominal torque Mn = 0.18 ÷ 197.6 Nm
• Rotation speed n = 640 ÷ 2960 rpm

Designation and duty
The normalized three-phase asynchronous motors, TN series, are suitable for generic use in industrial applications. They are self-ventilated motors (IC411) suitable for S1 type continuous duty and to be driven by inverter.

Certifications and options
Three-phase standard motors are available with ATEX Zone 2/22 - Category 3G/3D certificate and ATEX Zone 1/21 - Category 2G/2D certificate (for potentially explosive environments).

Standards
All M.T. Motori Elettrici motors are manufactured complying with IEC international standards.
