CHT 71 Single-Phase Aluminium Motor (0.25–0.55 kW)
CHT 71 single-phase aluminium motor — IEC frame 71, 2 / 4-pole, 0.25–0.55 kW, 230 V 50 Hz with a running capacitor (double capacitors, main and auxiliary, for high starting torque). Aluminium casing, IP55, class F insulation, IC411 fan cooling, duty S1. Mounting B3, B5 or B14 — the dimension sheet gives the frame 71 mounting dimensions.
How to pick from the table: choose the pole count for the speed you need, then the power; the capacitor column is the running capacitor fitted. The type letter is the motor's length designation within the frame.

Product Information
Reading the table
Single-phase 230 V 50 Hz motors with a running capacitor (double capacitors, main and auxiliary, for high starting torque). Each row gives the type, poles, rated power, speed, torque, current, efficiency, power factor and the capacitor rating; "Show starting and part-load data" adds the starting ratios and the rotor inertia.
Fitting to a gearbox
The frame size is the IEC size the gearbox flange is specified by — B3, B5 and B14 mounting dimensions are on the dimension sheet.
