c
The value 6 P (in watts) is based on practical observations and is considered to represent the majority of magnetic loads up to the maximum limit of P = 50 W, that is 6 P = 300 ms = L/R.
Above this, the loads are made up of smaller loads in parallel. The value 300 ms is therefore a maximum limit whatever the value of current drawn.
Slip ring motors:
starting, breaking
Squirrel cage motors:
starting, breaking while
motor running
Slip ring motors:
starting, plugging, inching
