The Mosolver is an innovative servo motion actuator which infuses a position feedback sensor into the very structure of a high pole count AC motor. This eliminates the need for costly encoder and resolvers.
By combining the motor and resolver into a single package, the Mosolver enables a compact, inexpensive and robust closed-loop motion control. Added sense coils within the motor allows for precise rotor position. Voltages are induced by the sense coils from a combination of the PWM current ripple and flux steering as a result of rotor and stator interaction.
The elimination of a separate feedback device reduces cost and size, eliminates alignment (and loss thereof) and greatly improves ruggedness of the system.
