CHT 90 Three-Phase Motor 6-Pole (0.75 kW)

Electric Motors — three-phase

CHT 90 three-phase motor, 6-pole (about 1000 r/min at 50 Hz) — Chiaravalli's IEC frame 90 aluminium motors in the IE3 efficiency class, 0.75 kW. Aluminium casing, IP55, class F insulation, IC411 fan cooling, phase separator, Δ/Y 230/400 V 50 Hz, RAL 9022 grey. Mounting B14 (face flange — our most common fit on gearboxes), B5 (flange) or B3 (foot): pick it in the table's Mounting filter; the dimension sheets give the frame 90 mounting dimensions.

How to pick from the table: choose the power, then the efficiency class — IE3 from 0.75 kW up (we supply IE3 and above only from 0.75 kW; IE1 below that) — and the mounting. 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

Every row is one motor of this frame and pole count: the mounting, the type letter (the catalogue's length code), 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.

Mounting

The table opens on B14 (face flange) — our most common fit on gearboxes. Switch the Mounting filter to B5 (large flange) or B3 (foot) for those versions; the electrical data is the same, the mounting dimensions are on the dimension sheets (B3 / B5 / B14 drawings and the frame table).

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.
