Abstract

The invention discloses a variable frequency motor and a water supply system. The variable frequency motor comprises an outer housing, a stator, a rotor and a frequency conversion module. The stator and the rotor are installed in the housing; the rotor has a rotation shaft; one end of the housing is an output end; the other end of the housing is a non-output end; one end of the rotation shaft is an output end; the other end of the rotation shaft is a non-output end; the output end of the rotation shat is projected out of the housing through the output end; an electric installation heat radiation cavity is formed on the output end of the housing; the height of the electric installation heat radiation cavity is extending along the axial direction of the rotation shat; the rotation shaft has a rotation shaft extension part for matching with the extension of the electric installation heat radiation cavity; and the frequency conversion module is positioned in the electric installation heat radiation cavity. The variable frequency motor reduces the integral volume of the variable frequency motor and improves the integration degree and the reliability of the variable frequency motor.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a variable frequency motor and a water supply system. Background technique [0002] At present, motors are widely used in people's daily life and industrial production, and the motors are basically designed with general motor technology solutions. The mismatch between the operating conditions and the design conditions will lead to extremely high operating efficiency and use efficiency of the motor. Great reduction. In order to solve the above problems, the motor is usually equipped with a frequency conversion module for speed control, and the frequency conversion motor mode appears, and this mode gradually replaces the traditional mechanical speed control and DC speed control schemes with its outstanding control advantages and wide application range. [0003] However, the variable frequency motors in the prior art need to be additionally equipped with control cabinets to install...
