5. Force / velocity profiles
These profiles assume the continuous working voltage is available across the motor (there are no amplifier limitations) and that there is an additional heatsink plate. The continuous ratings are for a maximum motor phase temperature of 100oC and include cooling effects from motor movement while peak ratings are for an initial motor phase temperature of 25oC rising to 100oC.
