Abstract :
When a voice-coil motor is used for cutting tool positioning under load forces, it is likely to have a high copper loss and, consequently, a high temperature rise. A novel solution that uses an auxiliary rotary motor is proposed. The design approach is discussed. A design example with simulations is given
