How to calculate the radial force of motor

1.

1. The calculation of the circumferential force of the belt pulley

first use the conversion ratio of the belt pulley speed and the belt pulley diameter, speed ratio = output speed: input speed = pitch circle diameter of the load belt pulley: pitch circle diameter of the motor belt pulley. The circular force and the reference force are the same, diameter - 2H = pitch circle diameter, h is the groove depth on the reference line, different types of V-belt h are different, yzab CDE, the circular force on the reference line are h = 1.62 2.753.54.88.19.6 respectively

2. Calculation of belt pulley radial force:

the radial force is the theoretical force of belt pulley pitch line position, which is generally expressed by PD, and the outer circle is generally expressed by OD. The conversion formula of pitch circle and outer circle is different for different groove types. Generally, it is easy to measure the outer circle of pulley, and calculate pitch circle according to the formula. SPZ:OD=PD+4; SPA:OD=PD+5.5; SPB:OD=PD+7; SPC:OD=PD+9.6

The axial force of the pulley is set as D1, N1 for the diameter and speed of the motor pulley (driving pulley) and D2, N2 for the diameter and speed of the driven pulley; That is, D2 = D1 * (N1 / N2). The minimum outer diameter of pulley a or spa is 80mm, SPZ belt, and the small pulley is not less than 63mm

extended data:

the recommended degree of pulley groove angle for different types of pulleys in different diameter ranges

1. The recommended degree of pulley groove angle for O-type pulleys is 34 degrees when the pulley diameter ranges from 50 mm to 71 mm; 36 degrees in the range of 71mm to 90mm, & gt; It is 38 degrees at 90mm

2. The diameter of A-type pulley is 34 degrees when the pulley diameter ranges from 71mm to 100mm, and 36 degrees when the pulley diameter ranges from 100mm to 125mm& gt; 38 degrees at 125 mm; When the diameter of B-type pulley ranges from 125mm to 160mm, it is 34 degrees; 36 degrees at 160 MM-200 mm, & gt; When 200 mm, it is 38 degrees

3. C-type pulley is 34 degrees when the pulley diameter ranges from 200 mm to 250 mm and 36 degrees when the pulley diameter ranges from 250 mm to 315 mm; 38 degrees at 315 mm

When the diameter of D-type pulley is 355mm-450mm, it is 36 degrees; At 450 mm, it is 38 degrees; E type is 36 degrees from 500mm to 630mm; It is 38 degrees when 630mm

2. It has been installed many times, but it has never been calculated. The torque transmitted by the motor through the tail shaft should be determined according to the actual size of the motor encoder. This is not determined by the motor, but by the size of the encoder.

3. The axial direction is the direction of the fan axis, the radial direction is 90 degrees horizontal with the axial direction, and there is a vertical direction, vertical is easy to understand

4. Formula: 9550 times the rated power of the motor divided by the motor speed = torque (n / M)
on this basis, divided by 9.8, we can get how many kilograms of weight the motor can pull
rated torque of motor
t (N.m) = (9550 × P ÷ N
t (N.m) / 9.8 = load (kg)
P: motor rated power
n: motor rated speed
t: torque (n / M)

5.

Motor torque:

the calculation formula is:

t = 9549 × P ÷ The unit of n is n & 8226; M (nm)

where: P rated power of motor (output power), kW

n rated speed of motor, R / min

specific calculation of speed n:

when the rotating magnetic field has

extended data:

generally speaking, the torque of motor with mechanical rotation is the torque of motor

Note: the torque of the motor is directly proportional to the strength of the rotating magnetic field, the current in the rotor cage bar, and the square of the power supply voltage, so the torque is determined by the factors of current and voltage

6. I've been doing it for months. It's not like that at all

7. Take bus No.2 at the south bus station and get off at the terminal.
take bus No.202 at the West bus station and get off at the terminal. It's very close. Take a taxi and you'll get there for about 10 yuan.
there's also a bus station for Zhuzhou and Xiangtan, just opposite the railway station and going north

8.

No.14, -- no.801 and No.2 at West passenger station; 606, 101; No. 201 -- No. 603 in passenger transport center; NO.609 -- Chang passenger transport center west station

Chang automobile passenger transport center

address: Fuhou West Street, urban area (Xuyuan international home Plaza)

9. 608 is garbage. Any driver wants to stop at the bus stop, but he is still running after the bus stop. He has a bad attitude to ask the way. Such a bus company is better than going home to feed pigs. The pigs are all proud of it. The thieves don't know how to step on the spot. The pigs of the bus company have no professional quality at all

10. Haining bus station is Haining passenger transport center, and Yanguan has Yanguan town and Yanguan scenic spot (that is, the place to watch the tide),
Yanguan town is in Guodian beside the East-West Avenue, you can take t113 or t221 to Guodian intersection in Haining passenger transport center, or t128 to Guodian in Haining passenger transport center
Yanguan scenic spot is the old Yanguan town on the edge of Qiantang River, where is the place to watch the tide and the ancient town of Yanguan. Haining passenger transport center can take bus T216 or T106 to Yanguan. If you want to hurry up, take Haining passenger transport center about 400 meters to Xinzhuang bus station on Haining Avenue and take T109 bus to Yanguan
in addition, at the intersection of Guodian, Yanguan town can take bus T109 to Yanguan (Yanguan scenic spot).
