Abstract

La presente divulgación se relaciona con motores eléctricos; la unidad de motor eléctrico puede incluir un rotor montado de manera axial en un vástago; el rotor puede incluir una pila de laminación central en un anillo de equilibrio; la pila de laminación de centro puede tener ranuras a lo largo de la circunferencia exterior que sujeta piezas polo unidas a una pluralidad de imanes. Los imanes pueden estar ubicados entre las piezas polo y la pila de laminación de centro. Los imanes pueden no estar totalmente contenidos en el cuerpo metálico del rotor; los componentes descritos del rotor pueden estar contenidos en un manguito de fibra envuelta; el rotor está montado de manera giratoria dentro de un estator.
