Cooling of motor spindles—a review [PDF]
The International Journal of Advanced Manufacturing Technology, 2020 AbstractThermally induced loads in motor spindles can cause a number of undesired effects. As a result, the process capability of spindles, and thus, the productivity of a process can decrease. Future motor spindles will be exposed to higher mechanical and especially thermal loads due to trends aiming to increase power densities and maximum speeds ...
