The starting resistor and the capacitor connected in series are connected between the energy end of the motor chip and the ground. In the brushless motor starter with low cost and direct current of the utility model, according to different power of the motor, the parameters of the resistor and the capacitor are reasonably selected and definite time-delay for the starting of the motor is carried out to guarantee normal work of activation I, activation II and activation III and avoid starting error after electric power supply is stable.
Description
Technical field
The utility model relates to a kind of dc brushless motor starting drive.Specifically, relate to a kind of low cost DC brushless electric machine starting device.
Background technology
Present motor starting device, open as on December 15th, 1999, publication number is that the Chinese invention patent prospectus that CN 1238593A name is called " apparatus and method that are used for brushless electric machine starting " discloses a kind of motor starting device.This starting drive comprises an inverter and a controller.Inverter has a plurality of switching devices that connect to the bridge-type of brushless electric machine supplying electric current.Controller produces the control signal of nuclear output control inverter switching device operation according to the output signal of magnetic field sensor.Before brushless electric machine starting, controller is exported control signal to start brushless electric machine according to the output signal of magnetic field sensor then by providing electric current with the location rotor at least between the two-phase of stator winding.As a result, no matter the position of p-m rotor before startup of motor how, all can obtain the output signal of stable magnetic field sensor, motor can reliably be started.This starting drive circuit complexity, the cost height.
Summary of the invention
The goal of the invention of the utility model motor starting device is to overcome above-mentioned deficiency, and a kind of low cost DC brushless electric machine starting device is provided.
For achieving the above object, the utility model low cost DC brushless electric machine starting device comprises motor chip, the drive circuit of motor is received in the output of motor chip top, bottom output, the running of control motor, on this basis, also comprise starting resistance and electric capacity that a series connection connects, starting resistance that this is connected in series and electric capacity are connected between the Enable Pin and ground of motor chip.
The goal of the invention of the utility model low cost DC brushless electric machine starting device is to realize like this, when dc power supply is powered, the incipient stage that power supply adds, because approximate short circuit of the initial stage of electric capacity charging, the Enable Pin voltage of motor chip is very low with making, motor chip is automatically locked, no-output, be that top output and bottom output are all locked, three of drive circuit, promptly drive I, drive II, drive III and all do not have driving, this section period, the voltage that drive I, drive II, drives III has been in the process of foundation.When capacitor charging time is finished, when the Enable Pin voltage of motor chip rises to operating voltage, the chip output automatic unlocking, the voltage that drives I, driving II, driving III is also set up fully, at this moment drive I, drive II, drive III and receive signal, motor starting device enters normal operating conditions.In the utility model low cost DC brushless electric machine starting device, according to different powers of motor, the parameter of choose reasonable resistance, electric capacity, electric motor starting is carried out certain time-delay, after power supply is stable, just can guarantee to drive I, drive II, drive the III operate as normal, avoid starting error.Starting resistance that employing is connected in series and electric capacity, starting resistance that this is connected in series and electric capacity are connected between the Enable Pin and ground of motor chip, have just saved the start-up circuit of special-purpose complexity, reach the goal of the invention that not only reduces cost but also guarantee stable normal startup.
