7.5kW 6 Pole IE3 (1000rpm) Teco AC Motor, IE3, B3 Foot Mounted, Aluminium, Frame D160M
MPN: I2----7-6B3
Alt. SKU: I276B3
Why Choose the TECO I2----7-6B3 Micro AC Inverter Drive?
The TECO I2----7-6B3 is a compact micro variable frequency drive designed for reliable speed control of three phase induction motors in light industrial, HVAC and OEM applications. Part of the proven TECO I2 series, it delivers stable V/F motor control in a space-efficient chassis suited to panel mounting.
This model is typically rated at approximately 0.75 kW (≈ 1 HP) and operates from a 380–480 V AC three phase supply. The 6B3 suffix indicates a 400 V class three phase input configuration within the I2 family.
How It Works
The I2----7-6B3 converts fixed-frequency AC mains input into a variable voltage, variable frequency three phase output using PWM switching technology. By adjusting the output frequency and maintaining a proportional voltage-to-frequency ratio, the drive controls motor speed smoothly and efficiently.
The inverter regulates acceleration and deceleration ramps electronically, reducing mechanical stress, limiting inrush current and improving process control compared with direct-on-line starting.
Key Features
- Rated motor power: ~0.75 kW (≈ 1 HP).
