Abstract
The invention relates to a starting method of a high load motor. The high load motor comprises an auxiliary drive motor and a main drive motor, wherein the auxiliary drive motor is a high-speed motor, the main drive motor is a low-speed motor, and the auxiliary drive motor and the main drive motor are in isolation connection through a magnetism transmission. The starting method includes that firstly, the auxiliary drive motor is started, and at this moment, the main drive motor is in a no-load zero-speed starting state; then the auxiliary drive motor drives the main drive motor to run through the magnetism transmission, the main drive motor is started when a revolving speed of the main drive motor reaches half of a work revolving speed, and simultaneously, loads are added to the main drive motor; and when the main drive motor reaches the work revolving speed under the drive of the auxiliary drive motor and the power drive of the main drive motor, the magnetism transmission is cut off, a power supply of the auxiliary drive motor is simultaneously turned off, and at this moment the main drive motor independently drives the loads.
Description
Technical field
The present invention is a kind of high capacity electric motor starting method.
Background technology
General large load motor is all relatively more difficult in the process that starts, and the motor device that has has designed auxiliary actuating apparatus, but starting effect distinguishes to some extent because of the difference of equipment, and the startup effect of some auxiliary actuating apparatus is very unstable.And the cost of present motor starting device is all higher, belongs to vulnerable equipment, uses and maintain all to have higher cost.
Summary of the invention
The purpose of this invention is to provide a kind of high capacity electric motor starting method, solve the problem of large load motor difficulty in starting.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of high capacity electric motor starting method, comprise auxiliary drive motor and main drive motor, described auxiliary drive motor is high-speed electric expreess locomotive, described main drive motor is slowspeed machine, to isolate connection by the magnetic speed changer between described auxiliary drive motor and the described main drive motor, at first start described auxiliary drive motor, this moment, main drive motor was in unloaded zero-speed starting state, then driving main drive motor by described auxiliary drive motor by the magnetic speed changer turns round, reach a half of working speed when the rotating speed of main drive motor, start described main drive motor, simultaneously loading on main drive motor; Under the drive of auxiliary drive motor, and under the power drive by main drive motor self, when main drive motor reaches working speed, disconnect the magnetic speed changer, cut off simultaneously the power supply of auxiliary drive motor, separately drive load by main drive motor this moment.
This high capacity electric motor starting method can drive stably by auxiliary drive motor, reduces motor and carry out some monkey wrench that cold start-up brings under load condition.
Description of drawings
The below is described in further detail the present invention with embodiment with reference to the accompanying drawings.
Fig. 1 is the structure chart of the described high capacity motor of the embodiment of the invention.
Embodiment
As shown in Figure 1, the described a kind of high capacity electric motor starting method of the embodiment of the invention, comprise auxiliary drive motor 2 and main drive motor 1, described auxiliary drive motor 2 is high-speed electric expreess locomotive, described main drive motor 1 is slowspeed machine, to isolate connection by magnetic speed changer 3 between described auxiliary drive motor 2 and the described main drive motor 1, at first start described auxiliary drive motor 2, this moment, main drive motor 1 was in unloaded zero-speed starting state, then driving main drive motor 1 by described auxiliary drive motor 2 by magnetic speed changer 3 turns round, reach a half of working speed when the rotating speed of main drive motor 1, start described main drive motor 1, simultaneously loading on main drive motor 1; Under the drive of auxiliary drive motor 2, and under the power drive by main drive motor 1 self, when main drive motor 1 reaches working speed, disconnect magnetic speed changer 3, cut off simultaneously the power supply of auxiliary drive motor 2, separately drive load by main drive motor 1 this moment.
This high capacity electric motor starting method can drive stably by auxiliary drive motor, reduces motor and carry out some monkey wrench that cold start-up brings under load condition.
