Question
Download Solution PDFThe torque developed by a motor while running at 1500 rpm is 206 N-m, and the shaft torque available is 200 N-m. The iron and mechanical losses, in watts, are:
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFPower flow in the motor
Input power - Armature loss = Developed power
Developed power - (Iron + Mechanical losses) = Shaft power
The relationship between torque and power is:
where, τ = Torque
P = Power
ω = Speed in rad/sec
Calculation
Given, τd = 206 Nm
τshaft = 200 Nm
Iron and mechanical loss = Pd - Pshaft
Iron and mechanical loss =
Iron and mechanical loss = (206 - 200) × 50 × π
Iron and mechanical loss = 300 π
