Tubular Motor for window and door

Q:What is the power of the motor: Dc motor power P = UI Ac motor power: P = 1.732 * U * cos phi Power = force * velocity P is equal to F times V minus the formula 1 Torque (T) = torque (F) * action radius (R) is F = T/R.Linear velocity (V) = 2 PI R * speed per second (n seconds) = 2 PI R * 60 per minute speed (n)/n = PI R * 3 points / 30 - formula Formula 2 and 3 enter formula 1: P = F * V = T/R * PI R * n / 30 = PI / 30 * T * n -p = power unit W, T = torque unit Nm, n points = revolutions per minute If you change the units of P to KW, then this is the formula: P * 1000 = PI / 30 * T * n 30,000 / PI * P = T * n 30000/3.1415926 * P = T * n P = 9550 T * n If we know that P, according to 9550P is equal to T times n, we know that the other one in the torque T and the velocity W is right

Q:What are the advantages of ac generators compared to dc motors? Why is it that today's big generators are talking about generating electricity and getting rid of dc power?: Alternator's advantage is the advantage of developing energy, now is the main ac power on the consumption of energy, and this kind of generator maintenance convenient, and durable. And dc generator for dc energy consumption only, in addition to small household electrical appliances is large motor with this kind of dc power supply, small home appliance is not necessary to buy a dc generator for power supply? And large motor, need large generators to supply power, to know the large generator driven by either hydraulic or mechanical energy or wind need to consume large amounts of diesel oil, water or wind, and want to have big permanent magnet iron core or high power rectifier devices. Permanent magnetic iron core is one of the best in the dc generator, but also need high power permanent magnet generating large generator drive, and is very difficult to start, or excitation coil dc power supply, need to control dc again. A lot of trouble. Instead of using alternating current, the whole flow can also save energy. This is just my personal opinion, I don't know if it's right or wrong.

Q:Which is better for a dc treadmill or an ac treadmill?: How are you Run ac electric motor with frequency converter, and frequency converter, dc, need not run on the market at present electricity is dc motor, dc motor is ac motor durable, cost is lower than ac motor, dc motor for household electricity run using frequency low unlike commercial electricity run continuous operation at the club for a long time, so there is no need to buy ac motor electrical run, of course, if your family has better conditions with ac motor.

Q:Permanent magnet motor is dc motor and ac motor: A permanent magnet can be a dc motor or ac motor (for example, a home breeze fan). In the same way, no permanent magnet can be either a dc motor or ac motor, or even an alternating current. In contrast to electric excitation motor, permanent magnet motor, especially rare earth permanent magnet motor, has simple structure and reliable operation. Small volume and light weight; Small losses and high efficiency; Flexible and varied in shape and size of the motor and other significant advantages, and application scope is extremely broad, almost throughout the aerospace, defense, the areas of industrial and agricultural production and daily life.

Q:Soybean milk machine ac motor or dc motor: Soybean milk machine motor and other small appliances chooses to supply the power source is communication, but into the motor coil is used through commutator after dc, the dc motor also includes excitation coil. It is not economical and unrealistic to use dc motors directly under current power systems. "Ac motor" is a machine used to realize mechanical energy and exchange electrical energy. Ac motor has become the most commonly used electric motor due to the huge development of ac power system. Compared to the ac motor and dc motor, with no commutator (see dc motor commutator), so the simple structure, easy fabrication, quite strong, easy to make a high speed, high voltage, high current, the large capacity motor. Ac motor power covers a wide range, ranging from a few watts to several hundred thousand kilowatts and even a million kilowatts. In the early 1980s, the largest turbine generator was 1.5 million kilowatts. [1-2] ac motor was invented by the American Serbian scientist nikola tesla.

Q:What is the speed of the general motors: The speed of the motor is also the rated speed of the motor. The speed of the motor at the rated power. The speed of the motor, which is full load, is also called full load speed. Use the symbol "n" to indicate the unit is "RPM". Two, different purpose and type of motor, different speed. Three, motor speed calculation of synchronous speed = 60 * the logarithmic frequency/poles (n = 60 * f/p) n -- -- -- -- -- -- -- -- motor speed (numble), unit: revolutions per minute (RPM) F -- -alternating current frequency (frequency), unit: Hz P - - the magnetic pole logarithm (pair), unit: right (p). 8 extreme: 60 * 50/4 = 750 RPM, and asynchronous RPM is slightly reduced by about 735 RPM.

Q:Is the squirrel-cage motor communicating in three phases?: The small and medium squirrel cage asynchronous motor can be directly started directly, the direct starting equipment is simple, the method is simple. But the starting current is large and the torque is small. Large capacity of squirrel-cage asynchronous motor starting, generally adopt the method of reduce the voltage of the stator winding step-down starting, can reduce the starting current, but also inevitably reduces the starting torque. Various step-down starting way is as follows: step-down starting starting star Angle conversion starting method since the coupling compensation Yanbian triangle starting voltage starting voltage drop coefficient is 0.577 times the rated voltage 0.78 * * rated voltage depends on the stator winding tap voltage rated voltage starting current voltage drop coefficient multiplied by the starting current (straight) a third * starting current (straight) depends on the stator winding tap voltage 0.6 * (straight) starting torque starting current multiplied by the square of the voltage drop coefficient * starting torque (straight) a third * starting torque (straight) depends on the stator winding tap voltage 0.6 * starting current (straight) starting method of characteristics Motor stator winding through autotransformer step-down starting, starting after removal of the autotransformer motor stator winding into a star, when starting or changed into triangles When the starter motor stator winding connect yanbian triangle after starting or changed into advantages and disadvantages of 1 small starting current

Q:Why should ac motors be used in parallel with capacitors: It is. The motor will not work. In order to be able to in the case of single phase can also produce a rotating magnetic field, the designers in multiple access a coil at the same time, through a capacitor on the coil, leading to join this coil phase voltage phase shift. So it's going to be a single phase in the outside and it's already going to be a double phase. The two phases produce a rotating magnetic field. The principle of connection is illustrated

Q:Electric curtain choice dc motor or ac motor?: Electric curtain commonly USES ac motor is the best, the ac motor is torque big, such as electric curtain of electric, electric curtain of electric curtain, shutter, Roman curtain, ceiling shade, etc. But now partial open curtain motor is involved in power failure manual function, dc motor voice is very small, adopt direct current electric control method. The performance aspect is also stable. The curtain machine should be selected according to the actual needs. Note that the quality of regular manufacturer is reliable.

Q:Three-phase ac asynchronous motor load start and start up with airload start current who small, why?: Load start current is large, and load start consists of idle start current and load current.
