Abstract

The utility model discloses a start device of a single-phase resistance start motor. The start device comprises a rotor composed of a main winding and an auxiliary winding which are connected in parallel. A switch is connected to an output end of the auxiliary winding, and a second auxiliary winding is reversely connected in series between the auxiliary winding and the switch. According to the start device of the single-phase resistance start motor, the second auxiliary winding is reversely connected in series to the output end of the auxiliary winding, so that the integral winding number of the auxiliary winding is reduced, the increased range of total resistance is large, the start torque is improved effectively, and the temperature rise in the motor can be further reduced without increasing the current density of the auxiliary winding.

Description

A kind of starting device of single-phase electricity resistance-start motor
Technical field
The utility model relates to the electric motor starting technical field, relates in particular to the starting device of single-phase electricity resistance-start motor.
Background technology
The starting device of single-phase electricity resistance-start motor generally includes the stator that is made up of main winding and auxiliary winding parallel connection, and the switch of the output of auxiliary winding connection.Wherein auxiliary winding works when electric motor starting, and behind electric motor starting, needs to realize breaking off, and main winding is used to realize steady operation.The auxiliary winding of traditional single-phase electricity resistance-start motor copper cash commonly used or aluminum steel, thus require total effective turn of auxiliary winding few, total effectively D.C. resistance is big, and ability and main winding form electric phase difference like this, make the motor normal starting.At present, directly reach the above object through the number of turn that reduces auxiliary winding and the line that reduces auxiliary winding usually, the auxiliary winding current density is big, auxiliary winding burns easily but said method is prone to make.
Summary of the invention
The purpose of the utility model provides a kind of starting torque that improves, and reduces the starting device of the single-phase electricity resistance-start motor of electric machine temperature rise.
Be the realization above-mentioned purpose, the starting device of a kind of single-phase electricity resistance-start motor of the utility model, it comprises the stator that is made up of main winding and auxiliary winding parallel connection, and the output of auxiliary winding is connected with switch, and said auxiliary winding and switch room differential concatenation have second auxiliary winding.
Adopt the starting device of the single-phase electricity resistance-start motor of the utility model; Output at auxiliary winding oppositely has been connected in series second auxiliary winding; Thereby the whole number of turn of auxiliary winding is reduced, and the amplitude that all-in resistance increases is bigger, effectively improves starting torque; And do not increase the current density of auxiliary winding, also can reduce electric machine temperature rise.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the starting device of the utility model single-phase electricity resistance-start motor.
Embodiment
As shown in Figure 1; The starting device of a kind of single-phase electricity resistance-start motor of the utility model; It comprises the stator that is made up of main winding 1 and auxiliary winding 2 parallel connections, and the output of auxiliary winding 2 is connected with switch 3, and 3 differential concatenations of said auxiliary winding 2 and switch have second auxiliary winding 4.
Adopt above structure, after the output of auxiliary winding 2 oppositely has been connected in series second auxiliary winding 4, thereby the auxiliary winding 2 whole numbers of turn are reduced; The amplitude that all-in resistance increases is bigger; Effectively improve starting torque, and do not increase the current density of auxiliary winding 2, also can reduce electric machine temperature rise.
