In vain, by three line pre-inserted motor 5 jacks, with electrostatic flatiron by indigo plant, black, it is solded into terminal the most respectively.Take off motor 5 to need to check
Firm welding and solder joint are full, without solder skip, connection weldering, rosin joint, few weldering and many welderings.DC brushless motor braking is generally to utilize motor
5 self carry out fast braking two kinds of simple ways, and one is dynamic braking, and one is short circuit braking, and dynamic braking is handle
The kinetic energy consumption of motor 5 is in outside braking resistor, and short circuit braking is at the stator winding of motor 5 the kinetic energy consumption of motor 5
On.Obviously dynamic braking is generated heat advantageously for reducing motor 5.But short circuit braking carries out any changing without need for hardware
Dynamic, simple and convenient is its prominent advantage, so the present embodiment uses short circuit braking.So-called short circuit braking refers to the energy when brake
Accomplish to allow motor driving metal-oxide-semiconductor on brachium pontis (or lower brachium pontis) all turn on and lower brachium pontis (or upper brachium pontis) cut-off state,
The threephase stator winding of motor 5 is all shorted.It is in the motor 5 of generating state, is equivalent to power supply and is shorted.Because winding
Resistance is smaller, so the biggest short circuit current can be produced, the kinetic energy of motor 5 is fast released, so that the instantaneous generation of motor 5
Braking moment greatly, it is possible to reach the effect of Quick brake.Motor 5 speed is the highest, and short circuit current is the biggest, and brake force is also got over
Greatly.But must take into the ability to bear that can not exceed metal-oxide-semiconductor, the most typically wait that motor 5 speed is reduced to a certain degree
Re-use short circuit braking.

Protecting system, battery core unbalance protection system, initiation of charge voltage detecting system；Tool protection device includes being arranged in casing 4
Motor overload duplicate protection system, the low temperature of electric supply installation and the high temperature protection system in portion, motor drive module overheat protector system
System, the under-voltage duplicate protection system of electric supply installation, battery core unbalance protection system and overspeed protection system.Thus analyzing can
Know, this utility model embodiment provide shunt electric crank, built-in two grades overcharge protection chip (4.275V/ joint) exist
The overvoltage protection of charger remained able to play the overvoltage protection to battery core after losing efficacy, and internal fuse is prevented from power supply
Device 1 short circuit, overload；It is charger first class of protection that voltage overcharges protection system (4.150V/ joint), electric supply installation low-temperature protection system
System (0～10 DEG C) is 2A constant-current charge, and electric supply installation low-temperature protection system (10～60 DEG C) is 4A constant-current charge, charger self
Temperature protection system temperature range be-20～86 DEG C, battery core unbalance protection system specifically act as the voltage between battery core
Differing by more than 2V and then stop charging, initiation of charge voltage detecting system is 1.0V/ joint；The software of motor overload duplicate protection system
Protection 80A, 0.25S, hardware protection 80A, 2S, the temperature range of electric supply installation low temperature and high temperature protection system is-26～70 DEG C,
The maximum temperature of motor drive module overheat protector is 120 DEG C, and the under-voltage duplicate protection system of electric supply installation is in the case of band carries
For 1.7V/ save, under no-load condition for 2.77V/ save, battery core unbalance protection system act as band load time battery core between electricity
Pressure differs by more than 0.23V and then stops electric discharge.
