4kW 6 Pole IE3 (1000rpm) Teco AC Motor, IE3, B5 Flange Mounted, Aluminium, Frame D132M
MPN: I2----4-6B5
Alt. SKU: I246B5
Why Choose the TECO I2----4-6B5 Micro AC Inverter Drive?
The TECO I2----4-6B5 is a compact micro variable frequency drive designed to provide dependable speed and torque control for three phase induction motors in light industrial, HVAC and OEM panel applications. Part of the TECO I2 drive family, this model offers reliable V/F motor control and essential protection features in a space-efficient panel mount enclosure.
The 6B5 suffix denotes a 400 V class three phase input variant. This specific configuration is typically rated around 0.37 kW (≈ 0.5 HP), making it a good match for smaller motor loads where smooth speed regulation and simple installation are key.
How It Works
The I2----4-6B5 uses high-frequency PWM (pulse-width modulation) to convert fixed-frequency AC mains into a variable voltage, variable frequency three phase output. By holding a proportional voltage-to-frequency ratio (V/F control), the inverter governs motor speed smoothly across a range of operating points while improving energy efficiency and reducing mechanical stress compared with direct starting.
The drive also electronically shapes acceleration and deceleration ramps, reducing inrush currents and helping protect driven equipment.
Key Features
- Rated motor power: ~0.37 kW (≈ 0.5 HP).
- Supply voltage: 380–480 V AC three phase, 50/60 Hz.
- Control method: V/F speed regulation for general purpose motor control.
- Output frequency range: 0–400 Hz (typical).

Frequently Asked Questions
What does the 6B5 suffix indicate?
The 6B5 designation indicates a three phase 400 V class input variant within the TECO I2 micro drive series.
Does this drive use advanced vector control?
The I2 series primarily provides V/F control, suitable for general purpose motor speed regulation. More advanced control modes like sensorless vector are usually found in higher-end TECO drive families.
Can this inverter improve energy efficiency?
Yes. By regulating motor speed according to demand rather than running at full speed constantly, the drive reduces wasted energy in variable torque applications.
Is the drive suitable for panel mounting?
Yes. Its IP20 enclosure is intended for indoor electrical cabinets and OEM panels.
