Re: [CAD_CAM_EDM_DRO] operating temp of stepper motors

Generally the nameplate temperature rating is actually the
'temperature-rise', usually over 40°C ambient. So 50°C over 40°C is
about 194°F ! Typically, you cannot hold onto anything over 155°F, so if
you can hold onto the motor, it's probably not too hot.
