  • SURGICAL INSTRUMENT MOTOR WITH INCREASED NUMBER OF WIRES PER PHASE SET AND INCREASED FILL FACTOR AND CORRESPONDING MANUFACTURING METHOD
    Publication number: 20230353001
    Abstract: A motor for a surgical instrument includes a rotor and a stator. The rotor includes a shaft and a magnet. The stator includes (i) a cavity in which the rotor is disposed, and (ii) a coil assembly. The coil assembly includes multiple phase sets. The phase sets include multiple sets of wires. Each of the phase sets includes multiple coils and corresponds to a respective one of the sets of wires. The coils in each of the phase sets are at respective positions about the rotor. One of the sets of wires includes at least three wires. The stator causes the rotor to axially rotate a surgical tool of the surgical instrument based on current received at the sets of wires.
    Type: Application
