Application No. 08/202,828
1. A circuit for driving current through the stator
coils in a motor comprising:
a first voltage amplifier having a first input for
receiving an input signal, having a second input for receiving
a feedback signal, and having an output;
a compensation circuit to compensate the output of
said first voltage amplifier;
a second voltage amplifier for receiving the
compensated output from said first voltage amplifier;
a means for selectively driving said stator coils
responsive to the output of said second voltage amplifier; and
a selectable current path for selectively discharging
current from said compensation circuit such that said
compensation circuit is discharged when said means for
selectively connecting the output is not connected.
The reference relied on by the examiner is:
Rhodes 4,319,173 Mar. 9,
1982
Claims 1 through 17, 19 and 21 through 24 stand rejected
