Overview
the motor is a variable-frequency, three-phase asynchronous motor exclusively designed for the tower cranes and other similar amplitude mechanisms. It is applied to the
amplitude mechanisms in very harsh working conditions such as construction site or open pit quarry
Features
With introduction of spline output shat, it has good mechanical bearing capacity and excellent assembly performance;
Motor installation interface has the same size with original tower crane (POITAIN series), making it easier for switching and upgrading of old products
The motor is a variable-frequency motor featuring a wide range of speed regulation, small starting current, big starting torque and overload ability;
A thermal protection component is buried into the in stator winding and wired into the motor temperature protection control system, making motor more safer and reliable;
New brake (national utility model ZL201101881732, ZL201120188164.3) with higher safety and reliability this reduces the maintenance time and cost compact structure, small volume, lightweight as well as high reliability, so it can be braked quickly and positioned accurately. It is suitable for frequent starting and raking
- Q: What is ac servo motor?
- I'd think a servo under dash that moves doors inside A/C and heat, defrost if you're talking automobile.
- Q: I'm going to start building an electric car soon, and i'm trying to understand everything about ac and dc motors, how they work, and which application would be best.
- There are many different types of AC motors. Very few of them have permanent magnets inside. An AC motor with permanent magnets is called a permanent magnet synchronous motor. A brushless DC motor is essentially the same thing as a permanent magnet synchronous motor. A brushless DC motor has an electronic commutator that can be an external controller or circuitry inside the motor. The electronic commutator converts DC power to a square wave approximation of AC.
- Q: I have a small 1/4 HP 220V AC motor, and I want to see if it will run on a regular household 120V AC circuit. Will it work?
- poorly. It will rotate slowly if at all, and may overheat. .
- Q: Is suppression capacitor (Volt AC) can be used as motor starting capacitor?
- I wouldn't try it. Capacitors have a maximum ripple current rating. The EMI cap doesn't have as high a rating as an oil filled motor start capacitor.
- Q: What will happen if i supply ac current To a dc motor?
- DC autos function in basic terms whilst dc modern is given.If we alter the polarity shaft will run in opposite direction.whilst u provide Alternating modern, created magnetic field retains it in a null factor ensuing the coil to get heated up and burned.
- Q: Is the permanent magnet synchronous linear motor AC motor or direct current motor?
- Permanent magnet synchronous motor (PMSM) is usually referred to as brushless DC motor with back electromotive force, trapezoidal wave and armature current as square wave. The back electromotive force and armature current are both sine waves, which are called permanent magnet synchronous motors.
- Q: I have an auger that is triggered every 5 seconds for 4 seconds. It spins at 1 rpm. brushless 120 VAC at .5 amp. It can handle about 100 inch pounds of torque. I don't have the ability to change the programming on the motherboard. That would be too easy. lolI want to decrease the rpm in half when I want to without burning up the coils of the motor in the mean time. Could I put a dimmer switch in series with the motor until it puts out 60VAC? I just figured it might get stuck trying to push the load and burn up. It is an expensive little motor to experiment on.Any ideas is appreciated
- Could I put a dimmer switch in series with the motor until it puts out 60VAC? it depends on the exact type of motor. universal or ac/dc motors can be speed controlled, but synchronous motors spin at a rate determined by the supply FREQUENCY so changing the voltage would do no good. Could I put a dimmer switch in series with the motor? no, dimmer switches produce spikes which would do your motor lots of no good, and produce catastrophic interference. And since its an inductive load you would also blow the dimmer.
- Q: Could anyone one please explain how the available torque for an AC motor varies with speed?
- Electrical Motor Torque Equation Torque can be calculated in Imperial units like T = Php 63025 / n where T = torque (in lbf) Php = horsepower n = revolution per minute (rpm) Alternatively Tft = Php 5252 / n (1b) where Tft = torque (ft lbf) Torque can be calculated in SI units like T = PW 9.554 / n where T = torque (Nm) PW = power (watts) n = revolution per minute (rpm)
- Q: ok i have a 95 nissan pickup and my ac went out the other day i can still feel cold coming out the vent the blower motor ant comming on i straight wired it 2 the battery and it works could my resister be bad does the resister have any thing to do wit the ground on the blower motor
- I THINK that it is right behind the blower motor under the dash. Follow the harness from the blower motor and it will lead you right to it. Hope that helps! Matt
- Q: I've replaced a blower motor in my home AC with a similar motor. It's the same 1075 rpm, but 1/2 hp instead of 3/4 hp (as the old one had). How will it affect my AC performance? Does this power rating matter? It seems that if it's the same squirrel cage and the same RPM,the air flow should be the same.Thank you.
- Yes, it does matter. The horse power rating has to do with the motors ability to turn and maintain a constant RPM under a given load. The manufacturer seems to think that a 3/4 horse power is needed to turn THAT fan. You can use it, but the turning RPM may be less than you need and the life of the motor will be greatly reduced. If it were me, I would use it, but order a 3/4 HP motor ASAP and replace it.
