Product Description:


This series motor adopts modular design. It consists of four parts: torque motor, eddy current regulator, electromagnetic brake and fan, which can be flexibly configured to
meet different customer demands. With introduction of a new special brake, it can cater for outdoor and high-altitude operations. The product has reached the international
advanced level with the patent for utility model. It is mainly used as a trolley speed-change gear for tower crane as well as other mechanical equipments requiring for
constant power and stepless speed regulation.

FeaturesConstant tension and linear speed, stepless speed regulation, frequent starting;
Special eddy current regulator for the motor realizes smooth startup or stop;
New special brake (national utility model ZL201120188173.2, ZL2011201881643). This ensures fast braking and accurate positioning with higher safety and reliability
Besides, manual release is possible;
The rotor is made of copper alloy with better mechanical properties and mechanical bearing capacity in the domestic industry;
Spindle is hot forged by alloy structural steel,with good overall mechanical perlormancc;
A thermal protection component is buried into the in stator winding, making motor more safer and reliable;
Compact structure, small volume, lightweight as well as high reliability, so itfeatures easy maintenance and repair.

Q:How are electric generators and motors not similar?
they're comparable in that they are built in an almost comparable style. they're based on the theory of electromagnetism. In a motor the rotor has cord coils which generate a pulsing magfnetric field whilst a contemporary is [undergone them. those fields work together with the electromagnetic coils fastened to the stator (they dont circulate). those coils additionally produce magnetic fields whilst a contemporary is undergone them. . In different words there is an interplay between 2 contraptions of magnetic fields generated with the help of the electromagnetic coils; one is pulsing , the different isn't. This interplay is one in all successive moments of charm and repulsion bby the interacting magnetic fields. This interest then motives the shaft to coach thereby producing mechanical capability. In a generator, the shaft is became with the help of a mechanical stress such as an engine. fastened to the shaft are coils which generate magnetic fields whilst a contemporary is undergone them. As those coils and magnetic fields bypass the coils fastened to the stator (the backside), they bring about a contemporary in those coils. This contemporary is then taken from the generator. A generator then only works in opposite to a motor. this is achievable to make vehicles and generatiors that have basic magnets and fields interacting with coils (electromagnets) to offer the wanted consequence yet those are no longer as useful as those which use electromagnetic coils particularly than basic magnets.
Q:Advantages of AC current?
Power is always generated as AC. Conversion to DC requires more equipment and will also experience losses in the conversion . AC works really for motors because you don't need brushes, so they more efficient. AC is also safer than the same voltage DC because DC will tend to grab you and not let you go but AC tends to throw you since it passes through 0 volts every cycle. High voltage DC can actually be transmitted more efficiently than AC but in order to justify converting it you need to be transmitting it along very large length of power lines. Oh and of course anytime you want to change the voltage you need to go back to AC, because that's what a transformer needs. That's probably one of the biggest reasons actually. I should credit Midatlantian for reminding me.
Q:What are the drawbacks to operating an AC motor beyond it's base RPM?
In Excess of the base speed ie the rated speed, the slip of the ac motor( s=(ns-n)/n) becomes negative . at negative slip the power gets fed back ie the MOTOR NOW ACTS AS A GENERATOR. .
Q:How to correctly identify AC fan motor wires?
Schematics should have been on the inside cover of the AC or you should have labeled what went to where when you took them off. While the new motor may be a direct replacement, they can often be universal fits and as you know, the colors and such may be different. There is usually a diagram that comes with them so you know what is what. Along with replacing the motor, it is a good idea to replace the capacitor to.
Q:What kind of motor are used in electric cars?
EV hobbyists typically use DC brushed motors, series wound, with field coils. These motors are relatively inexpensive and easy to work with. Newer AC designs, discussed below, require much more complex power controller circuitry. * More cutting edge designs use AC motors. The Volt and Leaf use AC synchronous designs. The Tesla, and upcoming Prius models use three-phase AC induction motors. The synchronous motors use powerful permanent magnets, which require rare earth metals. The induction motors have the advantage of not needing permanent magnets or rare earths. All the AC designs are highly efficient, and lend themselves well to regenerative braking. * EV motors run anywhere from 24 volts up to hundreds of volts. 120 volt designs are popular today with EV hobbyists. 200-400 volt designs are more common in large auto company designs. Higher voltages reduce the current carrying necessity of the wiring, making thinner, cheaper wiring designs possible. * In operation, an EV motor may pull 3,000 to 50,000 watts of power. A horsepower is about 750 watts, so just take the rated horsepower and multiply by 750 to get an idea of the maximum wattages.
Q:My oscillating fan starts up super slow then after a few minutes starts working normally?
There may be a large amount of dust inside the motor keeping the shaft from spinning freely. It also may be that the motor does have a problem. Is the humming noise much louder than normal? Usually this is a sign the motor is failing. Note that when the blades are spinning slowly, there is a chance the motor could overheat and possibly catch fire. Just to be on the safe side I would replace the fan. It also could be a problem with the oscillating mechanism. The fan motor also powers the oscillating mechanism. This mechanism could be bound up keeping the motor from spinning at its normal speed. Usually there is a knob or lever that disengages the oscillating feature. Try disengaging this and see if the problem goes away.
Q:What is RC Motor ? Is it AC or DC or Both ? What are its advantages & Disadvantages ? What are its application?
An RC motor is a d.c. motor used in radio controlled models.
Q:both wires are live on my ac motor?
If just one brush is hung up in the passage, it won't work. Maybe remove them and inspect the brush-guide assembly and ensure the new brush slides in all the way down to the commutator/slip-ring. You can file brushes to make them fit better. Also, it's unlikely the problem is a dirty armature as another answerer suggested. Just spin the motor by hand in both directions and try it again. If it doesn't run, it wasn't dirt causing it.
Q:If i have an ac motor and a gear box with 2 out put shafts will torque be halfed?
either shaft can deliver the full torque if the other is not loaded. The sum of the two loads has to be less than the specified torque, minus friction losses. yes, reducing the speed by a factor of 10 will increase the total torque output by that same factor, less friction. .
Q:is commutator present in ac motor?
Yes, universal motors as used in mains powered tools, drills, sanders etc. not only but also, special type motors. Try 2 sites below.
