100S Frame Motors

Standardised 100S Frame Industrial Motors

100S Frame Motors are standardised industrial induction motors built to IEC 100S dimensional specifications, offering 2.2 kW (3 HP) capacity in a compact, interchangeable frame size. The "S" designation refers to short-shaft length variant of the 100-frame family, used where space-constrained installations require predictable mounting dimensions.

Bombay Engineering Syndicate supplies Crompton 100S frame motors used in machine tools, packaging equipment, water treatment plants, HVAC installations, and small industrial machinery. The standardised IEC dimensions ensure direct replacement compatibility with installed equipment from any IEC-compliant motor manufacturer.

Available in 2-pole (2880 rpm), 4-pole (1440 rpm), and 6-pole (960 rpm) configurations at 415V/3-phase/50Hz with Class F insulation and IP55 protection as standard. Frame material options include aluminium die-cast (lighter, corrosion-resistant) and cast iron (more durable, heavier-duty applications). Mounting variants: B3 foot, B5 flange, B14 face, B35 combined.
