Servo motor cast-aluminum rotor with balance columns aligned with blades

Abstract

The invention discloses a servo motor cast-aluminum rotor with balance columns aligned with blades and belongs to the technical field of a servo motor. The rotor comprises a hollow cylindrical cast-aluminum rotor body, wherein the outer side of the cast-aluminum rotor body is provided with a cylindrical cast-aluminum rotor housing in a sleeving mode, the hollow cylindrical cast-aluminum rotor bodyis internally provided with a cast-aluminum rotor connection liner, a slim is arranged between the cast-aluminum rotor connection liner and the cast-aluminum rotor body, the inner side of the cast-aluminum rotor connection liner is provided with a hollow groove, an inner side of a groove wall of the hollow groove is symmetrically provided with a trapezoidal groove and an arc-shaped groove, two ends of the cast-aluminum rotor body are provided with the multiple blades and the multiple balance columns, and the blades, the balance columns and the cast-aluminum rotor body are combined through one-piece injection molding. The rotor is advantaged in that the balance columns and the blades are symmetrically arranged in a staggered mode, not only can the good heat radiation effect and lower heatradiation cost of the servo motor be realized, but also the structure of the servo motor is more compact, the noise is smaller during high-speed rotation, and heating is uniform.

Description

technical field [0001] The invention relates to a cast aluminum rotor of a servo motor, in particular to a cast aluminum rotor of a servo motor in which a balance column and fan blades are aligned left and right, and belongs to the technical field of servo motors. Background technique [0002] With the development of society, servo motors have been widely used in all aspects of people's production and life. The miniaturization and intelligence of electrical appliances have driven motors to continue to develop towards miniaturization and intelligence. Servo motors are used in servo systems. The engine that controls the operation of mechanical components is an auxiliary motor indirect transmission device. The servo motor can control the speed and the position accuracy is very high. It can convert the voltage signal into torque and speed to drive the control object. The servo motor rotor speed is controlled by the input signal. , and can respond quickly. In the automatic contro...
