The rotor current – blocked is the maximum effective current value showing stable conditions that will travel the electric motor stopped when the electric motor is powered at rated voltages and frequencies.
The NBR 17094 shows maximum values of current to the locked rotor due to the function of the rated power of the electric motor.
The indication of the locked rotor current is the electric motor JM3120 1.5HP nameplate is held directly and points out the value of the relationship between the starting current relative to the rated current.
The service system is the system that the electric motor is subjected when the electric motor is running and it covers the ranges that are empty, at rest or no power over their durations and sequence it in time. The electric motor is designed to operate on a continuous basis.
