Spindle motors have a feature called "Power Curve".
At low RPM motor works in so-called continuous torque mode where Torque output is a constant and power is climbing as RPM is rising.
Between 1000-2000 RPM a shift happens.
Motor starts working in continuous power mode where power remains constant, but torque keeps getting smaller.
At RPM close to maximum, RPM begins to taper off as well.
This behaviour causes problems when calculation available machine power as maximum power or torque are only available in a narrow window.
HSMAdvisor' Unique Power Curve compensation allows to accurately and safely predict power availability at any possible cutting speed.
This eliminates thread of stalling the spindle or burning up the motor.
