CHT 100 Three-Phase Aluminium Motor (1.5–3 kW)
CHT 100 three-phase aluminium motor — Chiaravalli's IEC frame 100 motors in the IE3 efficiency class, 2 / 4 / 6-pole, 1.5–3 kW. Aluminium casing, IP55, class F insulation, IC411 fan cooling, 230/400 V 50 Hz (Δ 400 V from frame 132). Mounting B3, B5 or B14 — the dimension sheets give the frame 100 mounting dimensions.
How to pick from the table: choose the pole count for the speed you need, then the power; the efficiency class is IE3 from 0.75 kW up (IE1 below that) — we supply IE3 and above only from 0.75 kW. The type letter is the motor's length designation within the frame. Voltage 400/690 V standard from frame 160 (other sizes on request); brake motors and Siemens motors available on request.

Product Information
Reading the table
Each row is one motor of this frame size: the type letter and pole count (a 4-pole motor runs at about 1500 r/min on 50 Hz, 2-pole about 3000, 6-pole about 1000), the efficiency class, rated power, speed, rated torque, current at 400 V, efficiency and power factor. "Show starting and part-load data" adds the starting torque and current ratios (Ms/Mn, Mmax/Mn, Is/In), the rotor inertia J0 and, for IE3 / IE4 motors, the efficiency at 75 % and 50 % load.
Efficiency classes
From January 2017 the EU regulation (CE) 640/2009 requires motors of 0.75 to 375 kW with 2, 4 or 6 poles sold in the European market to be at least IE3. Nusaf supplies IE3 and above only from 0.75 kW up — IE1 motors are listed below 0.75 kW only. Efficiency figures follow IEC 60034-30 / 60034-2-1.
Fitting to a gearbox
The frame size is the IEC size the gearbox flange is specified by — a gearbox listed for "IEC 80" takes a frame 80 motor in B5 or B14. Mounting B3 (foot), B5 (flange) and B14 (face flange) dimensions are on the dimension sheets.
