Claim 9:
10. A method of controlling electric machine comprising:
monitoring a parameter value of the electric machine having
a toroidal magnetic cylinder which includes a first magnetic tunnel segment having a NNNN magnetic pole configuration, and a second magnetic tunnel segment having a SSSS magnetic pole configuration positioned circumferentially adjacent to the first magnetic tunnel,
a coil assembly positioned within the toroidal magnetic cylinder, the coil assembly including a plurality of coils wherein the first or second magnetic tunnel segment surrounds a first number of coils of the coil assembly,
wherein the coil assembly is configured for the first number of coil phases and the plurality of coils is divided to create a subgroups of coils wherein each subgroup of coils is assigned to one of the first number of coil phases;

determining if the parameter value has reached a first target value; if not, continue to monitor the parameter value;
if the parameter value has reached the first target value, emulating a second number of coil phases for the coil assembly by simultaneously energizing a first subgroup of coils and a second subgroup of coils such that the first subgroup of coils and second subgroup of coils to act as members of a single coil phase group.
