At least one mat of one of hook type and a loop type material covers a substantial portion of a predetermined wire pathway on a work machine. , in vertebroplasty augmentation and kyphoplasty. The first delay element is coupled between the first output and the first input of the SR latch. Next, Vc and Vz* are added to produce final compensated torque boost voltage command Vt* and Vt* and Em* are added to produce q-axis voltage command Vq* of the inverter output voltage.
