IS 996 : 2025 Single Phase a.c. Induction Motors for General Purpose

ICS 29.160.01

ETD 15

1 SCOPE

This standard covers single phase a.c. induction motors of the capacitor types, shaded pole motors and split phase motors for voltage up to and including 250 V and having windings with Class B, Class F and Class H insulation (see IS 1271/ IEC 60085) and output up to and including 2 200 W.

Motors for use on systems complying to voltages and frequencies other than preferred (see 4) shall be considered as complying with this standard provided, they comply in all other respects. The voltages and frequency for which they are designed shall be stated on the rating plate.
