Overview
This series motor is a variable-frequency three-phase asynchronous motor exclusively designed for tower cranes and other similar dewing mechanisms. It is applied to the dewing
mechanisms in very harsh working conditions such as construction site or open pit quarry.

Features

With introduction of spline drive shaft, it has good mechanical bearing capacity;
The motor is a variable-frequency motor featuring a wide range of speed regulation, high efficiency, small starting current, big starting torque and overload ability;
A thermal protection component is buried into the in winding, making motor more safer and reliable;
Excellent dedicated variable-frequency insulation materials are adopted, improving greatly the insulation reliability;
Compact structure, small volume, lightweight, so it can be braked quickly and positioned accurately. It is suitable for frequent starting and braking;
YTRVFW series motor is provided with an eddy current brake on the basis of YTRVF series. It enables more smooth starting and deceleration braking, making the operation
more smooth and accurate

Users’Options:
This series motor is divided into F1 and F2
F1 with airvane brake;will be determined by the
F2 without airvane brake;users when signing the contract but an encoder interface can be reserved

Q:I am using a single phase ac electric motor (115 V, 60 Hz), and I need to calibrate the speed with some other equipment. What can I use to vary the output slightly around the max?According to the specs, it is only a 1.6 amp motor at max draw. For this reason, I am concerned about using a router speed control because the high resistance may just turn it off and on.Thanks a lot for your help!: A variable frequency drive is what you want. Any number of vendors supply them

Q:i have an ac 1 hp motor and when i rotate the motor with an 2T engine or any other which current does the mortor produces and i f the engine is rotating maximum at 500 rpm how much current does the mortor produces: if you want to generate electric power mechanically, don't use a motor. either that won't work at all, or it will be very inefficient. instead use an alternator, the kind used with automobiles is ideal.

Q:Just replaced the outside condenser units fan motor and it turns the opposite direction than the old one. Wires are correct. Switched the leads on the running capacitor and it didn't help. Any suggestions??: turn it off switch the yellow and orange that will change your rotation1 yellow to 1 orange as long as its a reversable motor

Q:How can a DC motor be changed into a three-phase AC motor with good performance?: If the direct replacement is used, the mechanical characteristics and the service life of the motor will be directly affected. But as a technical transformation project, there are also successful cases. Priority is given to the output torque to meet the mechanical requirements, and also to match the power.

Q:How do ordinary AC motors brake?: Reverse brakingWhen the motor cuts off the normal power supply, the power phase sequence of the motor stator winding is changed so that a reverse braking torque is generated.

Q:Winding of single-phase AC motor?: Single motor is divided into main winding, secondary winding, main winding is working, and negative winding is started. The three motors are divided into main and secondary windings, and the three sets of coils are all working.

Q:I was planning on building an electric car hopefully weighing around 500KG and i was looking at a three phase motor rated 52.3A at 400V and was wondering how to convert/invert the power from a single phase DC power from batteries, to a three phase AC power to run the motor, i have looked a inverters but they all say, that if you put a single phase power source into it you can only power a max of a 3Kw motor, so i was thinking if i could maybe use 2 inverters, not sure if thats possible or not, or if someone has had experience in this and know a way of doing this as i cant get mains power to a moving car, anyway if anyone knows how to do this please let me know, i would be so grateful as i have spent at least 24+ hours trying to research this.: you have selected an electric motor used for a diesel electric locomotive. they don't convert battery power to make 3 phase 400 volts. instead they use a diesel engine to run an electric generator. 52.3 amps at 400 volts would require 1740 amps from a 12 volt source. your car would need 10 giant 200 amp-hour batteries, that would be about 1000 kg of weight by itself. the only practical way to get 3 phase power from a DC source is with a motor-generator. think about it, using a motor to rotate a generator to run a motor is highly inefficient power conversion. you need to stick with a DC motor, one of reasonable size, that can be powered by a battery bank that weighs in at under half the total weight of the vehicle. 5 KW single phase is about the maximum power that can be generated by practical inverters. but you would not be able to run a 5 KW motor from that, because inverters have no surge capacity to deliver the start up motor current. that is another reason you need to stick with a DC only power system.

Q:what are the typical dimensions of a 100 hp ac motor?: Electric motors are larger than a gas engine of equivalent horsepower; on the other hand, the electric motor should run for years without any attention. I've worked with motors of this size in industry, and I would say a typical one would be 2.5 to 3 ft in each dimension and weigh on the order of 1500-2000 lbs.

Q:How to run a dc series motor in ac? Will it limit its characteristics?: hi. AC automobiles are designed and outfitted in a different way than DC automobiles. AC automobiles earnings on the 60 hertz clock of a capability line (or 50Hz in different countries) - this suggests the capability line ameliorations stages 60 cases a 2nd - to rotate, whilst DC automobiles are designed with the voltage point utilized. you are able to administration them the two, yet with different skill. the simplest to regulate is the DC motor (replace the skill (the voltage) and it turns slower or quicker.

Q:Is 3 phase AC induction motor specified in terms of Voltage, Current Power. I have heard that a motor can be operated over a range of volt, current power. then what do the rated values indicate. Also if a motor is specified as 48 V AC, 300A then can it be operated with a battery that could supply 48V DC... neglect all the losses the need for an alternator. Thanks in advance...: The rated voltage is nominal voltage for which the motor is designed. The voltage can vary by plus or minus ten percent or so and the motor will still deliver the rated power without overheating so much that its useful life will be significantly shortened. The rated power is the power that the motor can deliver to the load 24 hours per day, seven days a week at rated voltage and rated ambient temperature for its expected lifetime. If the load is a little higher the motor's life will probably not be effected too much particularly if the temperature is not always at the maximum. If the load is less than the rated power, the motor will probably last longer than expected. The power delivered will be only what it takes to drive the load, so it can be much less than the rated power, but the motor will be less efficient if the load is a lot less than the rated power. The rated current is the current that the motor draws when it is operating at the rated voltage and delivering the rated power. If the voltage and/or load are above or below the rated values, the current will be above or below the rated value. Over a small range of voltage variation, the current changes in the opposite direction as the voltage change so that voltage multiplied by current will be about constant. Any battery of any voltage and sufficient power delivery capability could supply power provided that the DC power is converted to an AC voltage and frequency that are appropriate for the motor.
