Control box for single-phase basket motor

Abstract

The invention relates a control box for single phase basket motor, a single phase basket motor, comprising two single phase motor bodies and a control circuit inside single phase motor bodies, wherein the control circuit comprises a transformer, a time relay, five contactors, a start capacitor and an air switch. The five electrical components are all installed in one control box and the top of the control box are provided sequentially from left to right with air switch, capacitor box, transformer and the middle of the control box is provided with time relay around which the installation positions of five contactors are provided. The lower part of control box is provided with line bank of motor control circuit for the connection between the electrical components and line bank and the line bank connects motor body through sticking out via conductor. The control box provided by the invention has starting capacitor and running capacitor for motor inside.Since basket motor is used outdoor, this design increases the rain-proof and preservative properties and stubbing phenomenon of capacitor during construction is also reduced, increasing safety factor and decreasing maintenance frequency.

Description

technical field [0001] The invention belongs to the field of motor equipment, in particular to a control box for a single-phase hanging basket motor. Background technique [0002] Due to the differences in construction sites, many construction sites cannot provide three-phase power supply, which limits the use of three-phase asynchronous electric hanging basket motors. The single-phase hanging basket special motor is a new product developed under the condition of urgent market demand. However, since the basket motor is a load-starting motor, it is required that the motor must have a large starting torque. The starting torque of a single-phase motor is generally lower than that of a three-phase motor, and the starting current of a single-phase motor has a great influence on the voltage drop, which directly affects its starting. Torque, in the course of research, it is found that it is difficult to achieve the effect of use. Contents of the invention [0003] The purpose of...
