When running
at 4000rpm with an applied voltage of 42v, a DC permanent magnet
motor develops 23.1W of output power. The motor has a theoretical
no-load speed of 6000rpm at an applied voltage of 42v.
What is the
motor output torque at 4000rpm in N-m, What is the motors
theoretical back-EMF constant, What is the motors theoretical
torque constant, What is the motors theoretical stall torque, What
is the motors armature resistance, What is the motors efficiency at
4000rpm when...
