Abstract
Have open type recovery temperature can insure the energization input that one end is connected to motor hall signal line in motor, the other end connects high temperature alerting signal line, and high temperature alerting signal line extends to outside motor or is connected to controller together with motor hall signal line.Have closed type recovery temperature can insure the energization input that one end is connected to motor hall signal line in motor, the other end is connected to the feeder ear of motor Hall.When motor reaches prompting temperature because the temperature that works overloadingly for a long time rises, open type can close in recovery temperature insurance, high temperature alerting signal line has high level output, and control alarm set send alerting signal reminding user slow down or stop have a rest, after motor temperature reduces, open type recovery temperature insurance can recover off-state, and high temperature alerting signal line is without high level output, and vehicle can continue to travel.If user sends follow-up the continuing of high temperature alerting signal at vehicle and sails; motor temperature raises further, and when reaching protection temperature, closed type can disconnect in recovery temperature insurance; motor Hall loses power supply and quits work; controller quits work, and motor quits work, and prevents motor from burning out; after motor temperature reduces; closed type recovery temperature insurance can recover closure state, and motor Hall restores electricity, and motor Hall, controller, motor can be resumed work.
Description
Technical field
The utility model relates to a kind of brushless motor for automobile, especially a kind of brushless motor for automobile having high temperature to remind defencive function.
Background technology
At present; the brushless motor that known battery-driven car and electro-tricycle use; as long as vehicle control device provides working current, electrical motor will run and provide propulsive effort, and motor itself does not have fender guard; if motor works overloadingly for a long time; temperature is too high, and motor Hall connection lead very easily occurs and gets loose, Hall burns even motor coil and burns; cause vehicle to travel, bring inconvenience and the economic loss of use to user.
Summary of the invention
In order to overcome the deficiency of the brushless motor unprotect device of current elec. vehicle; the utility model provides a kind of brushless motor for automobile having high temperature to remind defencive function; this motor can send alerting signal reminding user and slow down or rest of stopping when temperature reaches and reminds temperature; temperature raise further reach protection temperature time; disconnect motor Hall to power, motor Hall is quit work, and controller quits work; motor quits work, and reaches the object preventing motor from burning out.
The technical solution adopted in the utility model is, motor has maximum operating temperature, and setting protection temperature is lower than maximum operating temperature, and setting reminds temperature lower than protection temperature.Have open type recovery temperature can insure the energization input that one end is connected to motor hall signal line in motor, the other end connects high temperature alerting signal line, and high temperature alerting signal line extends to outside motor or is connected to controller together with motor hall signal line.Have closed type recovery temperature can insure the energization input that one end is connected to motor hall signal line in motor, the other end is connected to the feeder ear of motor Hall.When motor reaches prompting temperature because the temperature that works overloadingly for a long time rises, open type can close in recovery temperature insurance, high temperature alerting signal line has high level output, and control alarm set send alerting signal reminding user slow down or stop have a rest, after motor temperature reduces, open type recovery temperature insurance can recover off-state, and high temperature alerting signal line is without high level output, and vehicle can continue to travel.If user sends follow-up the continuing of high temperature alerting signal at vehicle and sails; motor temperature raises further, and when reaching protection temperature, closed type can disconnect in recovery temperature insurance; motor Hall loses power supply and quits work; controller quits work, and motor quits work, and prevents motor from burning out; after motor temperature reduces; closed type recovery temperature insurance can recover closure state, and motor Hall restores electricity, and motor Hall, controller, motor can be resumed work.
The beneficial effects of the utility model are: brushless motor Yin Wendu is too high burn before; motor temperature reaches reminding user when reminding temperature and slows down or rest of stopping; travel if user continues overload; then when motor temperature reaches protection temperature; disconnect motor Hall to power; force controller, motor quits work, prevent motor temperature from continuing rising and cause burn-down of electric motor, effectively can prevent the damage of motor and the economic loss of user.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is a kind of embodiment of the present utility model;
In figure: 1. open type can recovery temperature be insured; 2. high temperature alerting signal line; 3. closed type can recovery temperature be insured; 4. motor Hall; 5. the energization input of motor hall signal line.
Detailed description of the invention
There is open type recovery temperature can insure the energization input (5) that (1) one end is connected to motor hall signal line in motor, the other end connects high temperature alerting signal line (2), and high temperature alerting signal line (2) extends to outside motor or is connected to controller together with motor hall signal line.Have closed type recovery temperature can insure the energization input (5) that (3) one end is connected to motor hall signal line in motor, the other end is connected to the feeder ear of motor Hall (4).When motor reaches prompting temperature because the temperature that works overloadingly for a long time rises, open type can recovery temperature insurance (1) close, high temperature alerting signal line (2) has high level output, and control alarm set send alerting signal reminding user slow down or stop have a rest, after motor temperature reduces, open type recovery temperature insurance (1) can recover off-state, and high temperature alerting signal line (2) is without high level output, and vehicle can continue to travel.If user sends follow-up the continuing of high temperature alerting signal at vehicle and sails; motor temperature raises further, and when reaching protection temperature, closed type can recovery temperature insurance (3) disconnect; motor Hall (4) loses power supply and quits work; controller quits work, and motor quits work, and prevents motor from burning out; after motor temperature reduces; closed type recovery temperature insurance (3) can recover closure state, and motor Hall (4) restores electricity, and motor Hall (4), controller, motor can be resumed work.
Claims (2)
1. the brushless motor for automobile having high temperature to remind defencive function; it is characterized in that: have closed type recovery temperature can insure the energization input (5) that (3) one end is connected to motor hall signal line in motor, the other end is connected to the feeder ear of motor Hall (4).
2. the brushless motor for automobile having high temperature to remind defencive function; it is characterized in that: in motor, have open type recovery temperature can insure the energization input (5) that (1) one end is connected to motor hall signal line; the other end connects high temperature alerting signal line (2), and high temperature alerting signal line (2) extends to outside motor or is connected to controller together with motor hall signal line.
