how many watts is a 1.5 hp motor
About 1,119 W: 1.5 mechanical horsepower (550 ft·lbf/s each) is approximately 1,118.55 W using this tool’s definition (~745.70 W per hp).
Detailed answer
This converter uses US mechanical horsepower: 1 hp = 550 ft·lbf/s ≈ 745.69987 W. Multiply 1.5 by that factor for shaft power in watts. Actual motor electrical input will be higher because of efficiency losses.
Relationship context
Horsepower is common on motor nameplates; electrical design and breakers are often sized in watts or kilowatts. Metric horsepower (PS) differs slightly and is not used here.
