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: i need to use an electric motor and i need to know how to change it to dc
- Basically you can't change the motor. You might be able to use an inverter which synthesises AC from the DC supply. As you give few other details I can't go any further on this one.
- Q: cost of car AC motor blower?
- Keyboard not working? Go to any autoparts store onine and key in your year, make, and model and search for blower motor. Then guess what? It tells you the price. Why would you ask us to do that for you?
- Q: I have this 12V 7Amps DC Dry Cell Battery please see image below
- Ac Aquarium
- Q: I used my ohm meter and find the pairs and number at random, 6-3, 5-2, 1-4, then I found my last 3 leads that showed continuity and number at random 7-8-9...then I wired the motor for 208 3ph as follows, 4-5-6- togethers,then 7-1 for line 1, then 8-2 to line 2, and 9-3 to line 3, the motor it is not grounded and the leads are not open, m' I missing something or the motor it's not good?
- **** in it
- Q: I am trying to figure out how to make an bench grinder that has an AC motor with a DC power supply with out buying an expensive inverter. This is for class project and we are on a budget.
- Can you tell us something more about the motor ? I think if we knew what kind of AC motor it is we could know about the construction and that will make it easier for us to think of a way to run it on DC supply. I think you might need a Brush and Slip ring assembly to be mounted on the same shaft as the motor so that the DC gets Converted in to AC.
- Q: I am looking to use a dc motor to power a very small, high speed fan. I need it to equate as closely as possible to a 110v 1600 rpm 1/70hp ac motor. Any suggestions would be appreciated.
- Go by the equivalent of torque in specific speed (example foot pounds)
- Q: How do I know whether the motor is a direct current motor or an AC motor?
- Look at the nameplate, such as AC 220, V is AC motor, DC 220 V is DC motor!
- Q: Hey, i was wondering if a fan motor by modifying it could be converted into a generator. do you think its possible and if so how? useful links will also be appreciated
- Oh man I just Loved jenifers answer - very practical! For the simple reason it is impossible to reasonably convert a single phase induction motor to be a generator of useable electricity ...
- Q: I am trying to make a rotating bb target. I went to Radio Shack and they got these little electric motors but they spin way to fast.....o.....lo -O-o .....l .....o It would be shaped something like this (above). The motor would turn the center and 4 targets are connected with a 3 inch metal rod to the center. Total length is about 9 inches, 2quot; tin disk targets and the center would be like a 3quot; tin diskIf this makes any sense? Any ideas and what power motor do you think I would need and how to do this? I am beginner when it comes to electric motors. AC would be prefered but DC will still be ok.

- Q: I have a large shop fan that is belt powered by an electric motor. Here a while back the fan stopped running and would just hum when it had power. If you pushed the fan blades it would start running. That told me that the likely suspect was the starter capacitor. Today I went to Grainger and picked up a replacement. Unfortunately they did not have a direct replacement but verified that the one they had would work. Came home.. hooked it up.. and it still will not start on its own. Although I did not mark down how it was connected months ago when I took it apart, it is only two wires and I could tell on the original piece where they were connected. Am I missing something here? Is there more to replacing a capacitor than just wiring a new one up? Or is there something else wrong. Thanks in advance!
- what is the voltage of the motor? does the fan turn freely without the belt? does the motor shaft turn freely? if there is a bind in the motor then that may be what is preventing it from gaining momentum. try to run the motor without the belt. you may just need a new motor. EDIT: if the motor runs freely when disconnected than make sure nothing is binding up the fan... try some WD40 until the fan spins effortlessly... if that doesn't work than you probably need a new motor. The commutators, brushes and springs the others are talking about are mostly found on DC motors. you have an AC motor. your motor is probably a dual-voltage... i.e can be wired for 120V or 240V... make sure it is wired correctly by looking at the motor name plate/wiring diagram.
