What is the speed of btca8s 1500W

1. You read the manual carefully to see how much current the fast charger can output. The 1500 Watt motor is not so easy to drive. It requires a current of 1500W / 60V = 25A. As the starting and uphill will require a large current, the charger must be more than 50A to be effectively used in this brush motor.

2. The same speed, but the power is not the same, the power consumption is certainly not the same, it may be that when his wattage is very low, the speed will be reced accordingly, high speed, its speed will increase, and then the wattage will increase.

3. First of all, the recer will change the torque and speed, not the power. If the efficiency of the recer is considered, the power will be reced< The origin of 9550:
the relationship among motor power, torque and speed
power = force * speed
P = f * V --- Formula 1
torque (T) = torque (f) * radius of action (R)
derived
F = t / R
--- formula 2
linear speed (V) = 2 π R * speed per second (N seconds) = 2 π R * speed per minute (n minutes) / 60
= π R * n score / 30 --- formula 3
substituting formula 2 and 3 into Formula 1,
P = f * V = t / R* π R * n score / 30
= π/ 30 * t * n min
--- P = power unit W,
t = torque unit nm,
n min = speed unit RPM
if the unit of P is changed to kW,
then the formula is as follows:
p * 1000= π/ 30*T*n30000/ π* P = t * n
30000 / 3.1415926 * P = t * n
9549.297 * P

9550 is the approximate value of 9549.297.

4. It must be 24000
2mm double edge flat bottom 20000-24000
brass and aluminum are relatively soft materials, and there is no problem at high speed, so it does not hurt the knife

5. The same basic parameters of the motor, generally around 400 yuan

6. There are three main differences between 1200W and 1500W (same type) motors: power, dimension and price; The principle of motor replacement is: 1.5kw can replace 1.2kW (1.2kW motor cannot replace 1.5KW)
(2). The situation of using low-power motor to replace high-power motor (bull for calf):
sometimes it is found that the 1.2kW motor is very hot and often burns the motor, so 1.5KW motor can be considered to replace 1.2kW motor, but when 1.5KW motor replaces 1.2kW motor, the current increase after 1.5KW motor is replaced should be considered, and whether the drive circuit can withstand it, such as increasing wires, contactors, etc The frequency converter (or other drive circuit) and the action range of the adjustment protection circuit
(3) the case of replacing high-power with low-power (big bull pulling trolley):
for some machines with large power margin, the measured power of 1.5KW motor is not greater than 1.2kW, in order to save power, 1.5KW can be directly replaced by 1.2kW motor; Three ways to change large motor into small motor: don't overload the current, don't burn the temperature rise of the motor, and see whether the motor runs continuously or instantaneously. The power margin of the motor in continuous operation should be larger
(4) for complex automatic control system, it is better not to change the original circuit structure< On the size of the motor, there are: the total length of the motor, the diameter of the shaft, the height of the shaft center, the mounting size of the base, etc.
if the motor size is the same, it is called direct replacement; if the motor size is different, it is called indirect replacement; if the shaft diameter is different, the pulley needs to be replaced; if the mounting size of the base is different, the mounting hole needs to be changed, If the center height is different, the transmission system should be readjusted
sometimes 1.2kW and 1.5KW motors share the same base, which will bring convenience for direct replacement
three. On the price (omitted)
(Note: 4. The motor can be divided into motor and generator, and the general replacement principle of generator is opposite to that of motor)
if it is not thoughtful, please add, thank you< br />、

7. The speed of electric vehicle motor is related to the number of magnetic poles. The less the number of poles, the faster the output is. The more the number of poles, the slower the output is. 1500W refers to the motor power, and 13 inch refers to the outer diameter of the motor. Generally, the larger the motor disk is, the more poles there are. According to your motor data, it should be an electric tricycle motor, and the fastest speed should be about 30km / s.

8. It's OK to add a frequency converter, but it should be greater than 1500W, or install a silicon controlled speed regulator to rece the starting current and start slowly to full speed

9. If the frequency conversion motor, you can change the frequency to control the speed, if the ordinary motor, you need to add frequency conversion control in the control program

10.

can run about 20 kilometers. The speed of 1500W is 180 / h

but the time is determined by the capacity of the battery, because the motor determines the speed and the capacity determines the time

the continuous driving range of electric vehicle is related to road condition, driving speed, load, motor power and battery capacity
if you want to know the approximate driving distance under such conditions, you can only divide (actual capacity of battery) by (actual driving current) to get (discharge time), and then multiply (discharge time of battery) by (running speed) to get the driving distance

since these parameters are variables, only approximate values are calculated
