11kW 2 Pole IE3 (3000rpm) Teco AC Motor, IE3, B5 Flange Mounted, Aluminium, Frame 160M

Why Choose the TECO I2----7-2B5 Micro AC Inverter Drive?

The TECO I2----7-2B5 is a compact and cost-effective micro variable frequency drive designed to deliver reliable speed and torque control for three phase induction motors in light industrial, HVAC and OEM panel applications. As part of the TECO I2 series, it combines straightforward V/F motor control with essential protection and configurable I/O in a space-efficient enclosure suited to electrical cabinets and machine integration.

This specific variant typically corresponds to a ~0.75 kW (≈ 1 HP) output rating on a 200–240 V AC three phase supply. The 2B5 suffix indicates a 200 V class, three phase input configuration within the I2 drive range.

How It Works

The I2----7-2B5 uses pulse-width modulation (PWM) to convert fixed frequency AC mains into a variable voltage and variable frequency three phase output. By proportionally adjusting voltage with frequency (V/F control), the inverter smoothly regulates motor speed while maintaining torque characteristics suitable for general purpose and variable torque loads.

The drive also manages acceleration and deceleration ramps electronically, reducing mechanical stress on driven equipment and improving start/stop behaviour compared with direct starting.
