Overview

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: What is AC used for as is without being rectified into DC first, if anything?: AC is the simplest way to distribute electricity, especially over long distances. If DC is needed, as in electronics, the AC is easily rectified. The vast majority of motor driven appliances have AC motors, and heating elements (stoves, water heaters etc.), work directly on AC just like they would on DC.

Q: Is this the part that controls wether i get cold or hot air? Please give lots of detail about the location of this part.Thanks: Yes it controls the blend door inside the plynum so its called a blend door acuator.Its either a acuator motor or vacuum controled diaphram thats located in the plynum,basically the giant plastic box mounted inbetween the dash and fire wall near the heater core.Would have to rip up the dash to get to,and would be a good idea to get a chiltons or take it into a shop, its a big job..GL

Q: difference between Ac and DC electric motors?: DC motors often use permanent magnets in which case you can't use them on AC. However there is a class of motor that can be equally used on AC and DC and these have a field winding instead of a magnet. Other AC motors depend on a phase shift and you can't do this in DC. Wikipedia explains all the different types of electric motor.

Q: the motor is 580 watts ac motor 11000 rpm 50hz i need to know the hp of the motor: 1 horsepower (hp) = 745.699872 Watts Therefore, 580 Watts = 0.777792812 hp.

Q: Criterion of selection between a AC and a DC motor advantages and the disadvantages of them?: Since you are asking for the criterion of selection, here it is.. AC motors have two coils: an outer coil to produce magnetic field, and an inner coil to produce counter electric field. DC motors have an outer magnet, and an inner electric field. DC motors need DC voltage supply, and since all of the household supply is AC conversion is needed (thus making DC more inefficient, although the loss is minor) AC motors give better torque than similar DC motors. Since AC motors have two ciols, the magnetic field between the two colis can be adjusted to give maximum efficiency or power (something that DC motors cannot do)

Q: AC motor speed regulator: AC motor is the most ideal speed control mode of frequency conversion, and other ways are electromagnetic speed regulation, variable pole speed regulation, variable pressure speed regulation.

Q: now i am using one dc 130 bhp motor for my crane. i want to change the motor to ac type, so what should be ac motor hp that equal to 130 hp dc motor.: A horsepower is a horsepower. It is defined as 550 foot-pounds per second, exactly equal to 746 watts. A bhp is a horsepower. Nobody has any idea where the 'b' came from or what it means. Back in 1962 I witnessed an argument that went on for over an hour in a college dorm, one side saying it stood for brake horsepower and the other insisting it meant blown horsepower, and neither side knowing exactly what those terms meant either.

Q: Technician came into my house and said that the capacitor and FASCO York Exhaust Inducer Motor 7021-9428 702110300 needs to be changed.I bought these two items,changed capacitor only and everything is working.that motor is on the roof inside of the metal box.It looks like this motor just cools all the electrical inside.So I connected old motor back but I could't check if it works or not.If anybody knows how can I check if it rotates or not please let me know.If it works I could save some money.Thanks.: You are either misunderstanding the components or not using the proper wording. It appears to be a bit of each. Please repost your question with specifics. An exhaust inducer is a component of a heating system.

Q: Hi,I planning to buy a aquarium filter form ebay which works on 120vac 60hz . i stay in India where voltage is 220vac 50hz .this filter is having a permanent magnet rotor. please help me can this motor work if i use a voltage converter (220v to 120v ) .Is frequency mismatch does not matter please help: for many AC autos, you will would desire to de-fee the utilized voltage fee on account that at a decrease utilized frequency the magnetic flux interior the gadget will strengthen that may strengthen currents interior the windings. some autos are designed for a 50/60Hz variety and artwork advantageous on the two frequencies, yet examine with the motor nameplate or producer. So, for a gadget designed for 60Hz engaged on a 50Hz device, set the utilized voltage to (50/60)*rated_voltage. OR, there are sturdy-state induction motor drives available which could take single section AC at 50Hz and convert that to a variable frequency voltage on the output (i think of you are able to variety the voltage fee as nicely). So purely alter the output to 60 Hz. this may be a plausible answer, albeit a sprint intense priced and there will be some ability losses interior the force.
