These high power density motors are beneficial for these types of applications because they offer increased torque in a smaller package size. This enables smaller motors to be used in order to reduce the overall package size and weight of the product. Higher power density leads to a motor efficiency increase as well. Patient comfort is increased by lighter devices that are able to run longer before battery changes/charges are needed. Another advantage is the extension of the lifetime of the motor, allowing the patient to continue using the same device for a longer period of time.
