Abstract
A kind of high load 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, connect carrying out isolation by magnetic speed changer between described auxiliary drive motor and described main drive motor, first described auxiliary drive motor is started, now main drive motor is in unloaded zero-speed starting state, then main drive motor is driven to operate by described auxiliary drive motor by magnetic speed changer, when the rotating speed of main drive motor reaches a half of working speed, start described main drive motor, loading on main drive motor simultaneously, under the drive of auxiliary drive motor, and under power drive by main drive motor self, when main drive motor reaches working speed, disconnect magnetic speed changer, cut off the power supply of auxiliary drive motor simultaneously, now drive load separately by main drive motor.
Description
Technical field
The present invention is a kind of high load motor starting method.
Background technology
General large load motor is all more difficult in the process started, and some motor devices devise 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, use technology maintenance gets up all to have higher cost.
Summary of the invention
The object of this invention is to provide a kind of high load motor starting method, solve the problem of large load motor difficulty in starting.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of high load 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, connect carrying out isolation by magnetic speed changer between described auxiliary drive motor and described main drive motor, first described auxiliary drive motor is started, now main drive motor is in unloaded zero-speed starting state, then main drive motor is driven to operate by described auxiliary drive motor by magnetic speed changer, when the rotating speed of main drive motor reaches a half of working speed, start described main drive motor, loading on main drive motor simultaneously, under the drive of auxiliary drive motor, and under power drive by main drive motor self, when main drive motor reaches working speed, disconnect magnetic speed changer, cut off the power supply of auxiliary drive motor simultaneously, now drive load separately by main drive motor.
This high load motor starting method, can be driven stably by auxiliary drive motor, and reduction motor carries out some monkey wrench that cold start-up brings in the loaded state.
Accompanying drawing explanation
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is the structure chart of high load motor described in the embodiment of the present invention.
Embodiment
As shown in Figure 1, a kind of high load motor starting method described in the embodiment of the present 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, connect carrying out isolation by magnetic speed changer 3 between described auxiliary drive motor 2 and described main drive motor 1, first described auxiliary drive motor 2 is started, now main drive motor 1 is in unloaded zero-speed starting state, then main drive motor 1 is driven to operate by described auxiliary drive motor 2 by magnetic speed changer 3, when the rotating speed of main drive motor 1 reaches a half of working speed, start described main drive motor 1, loading on main drive motor 1 simultaneously, under the drive of auxiliary drive motor 2, and under power drive by main drive motor 1 self, when main drive motor 1 reaches working speed, disconnect magnetic speed changer 3, cut off the power supply of auxiliary drive motor 2 simultaneously, now drive load separately by main drive motor 1.
This high load motor starting method, can be driven stably by auxiliary drive motor, and reduction motor carries out some monkey wrench that cold start-up brings in the loaded state.
