Abstract
An electric machine includes a motor assembly including a motor controller including an NFC tuned circuit. The electric machine also includes a motor housing defining an interior space and enclosing the motor assembly within the interior space. The electric machine further includes an electric machine housing. The motor housing is enclosed within the electric machine housing. The electric machine also includes an NFC antenna mounted within the electric machine housing and configured to emit a magnetic field at a selected frequency. The magnetic field is configured to induce an electric current in the NFC tuned circuit. The electric machine further includes a memory configured to store information included in signals transmitted between the NFC antenna and the NFC tuned circuit via the magnetic field.
