Overview

YZPE2 variable-frequency three-phase asynchronous motor for lifting and metallurgy purposes is developed according to the characteristics of the
available tower crane, based on almost 10 years of experience in R&D of primary hoisting motor brake for the tower crane and metallurgy variable-frequency
motor. Lt is mainly used as a lifting mechanism of the tower crane, and also a trolley mechanism of heavy-duty crane

Features

A variable一frequency special motor is equipped, available with a wide range offrequency conversion, small starting current and big starting torque;
A thermal protection component is buried into the winding, and can be wired into motor temperature control& protection system, making the motor
operation more secure and reliable;
Strengthened inter-turn insulation is adopted in the stator winding, so the insulation reliability is higher;
Equipped with axial一flow fan or centrifugal fan, with good cooling effect and lower motor temperature rise;
Special bearing is adopted for variable一frequency motor, so it's more suitable for variable一frequency operating environment;
The rotating shaft is subject to alloy steel heat treatment, showing better mechanical strength;
The brake (fitted with special manual release device) is a de-energized brake type (national utility model patent, Patent No. ZL201120188124.9), with big
braking torque and short response time

Users’Options:

A rotary encoder can be set at the end ofthe motor as per the user demands, so a speed closed-loop control system isformed to make adjustment more reliable and accurate. The encoder model isconfirmed by the users when signing the contract

Q:Is the single-phase carbon brush motor a direct current motor or an AC motor?: (1) motor is a DC motor with single-phase brushless motor or AC, there is also some DC motor AC and DC motor, such as most of the pistol electric drill AC and DC motor, AC and DC power can also be used to use.(2) the power supply of rectifier bridge is not from positive and negative pole, and the power supply of rectifier bridge must have positive and negative poles, otherwise it is not power supply of rectifier bridge.(3) bidirectional thyristor should be used in AC circuit. If your motor speed is bidirectional thyristor, it may be AC and DC motor.DC motor carbon brush and AC motor carbon brush is the same, so there are AC and DC dual series motor.

Q:3/4 HPVOLTS 230/460 1725 RPM FRAM 42CYZHZ 60: It is an AC motor and it is a 3 phase motor. Have an electrician, wire it up for you if it does not have wire with plug, since you have to ask this it is best that, you get a professional to hook it up. You can destroy the motor or worst you can kill yourself. It also should say single phase, dual phase or 3 phase, some place on the motor. If not, on inspection a good knowledgeable person can figure it out.

Q:This is crazy but since i work under someone else i have no choice but to ask for help. My boss has a 3450 RPM, 60 cycle, 1 phase, 115/230 volts, 12.4/6.2 amps. Here's what we need to do other than buying a different motor. A pig will be roasted under a BBQ pit. I need to use this power-full motor and add some kind of extra belts to pulleys or something like that. We need to make this pig rotate at a much and i mean much slower rate so i cooks nice and thoroughly. My dead line is 6/26/09 If anyone has any brilliant ideas plz help.: This Site Might Help You. RE: How can i slow the RPM on an AC motor? This is crazy but since i work under someone else i have no choice but to ask for help.

Q:DC three phaseField voltage 150/300Full load amps field 8.64-7.7/4.32-3.85: The DC field amps don't tell you anything about the 3 phase AC (not DC) windings. That is the defining thing, the power for energizing the field is given- that is part of the calculation, but not the bigger part.

Q:the motor was connected to three phase source but now I want to connect it to the single phase source how can I make this: 1] If you connect the two lines of a single phase power feed to two of the leads on a 3 phase motor it will not run and will burn out. 2] Your ONLY choice is to make 3 phase. 3] You can do that two ways; one is to get a VFD

Q:What is the best choice?AC motor , DC motor, or Capacitor Start motor? Thanks!: I prefer a DC motor. A rheostat can be used to control voltage/RPM speed and DC motors are more reliable.

Q:Its a squirrel cage motor from a microwave fan. It has five wires; white, yellow, orange, red, and blue. Inside, it has 16 electromagnets on the stator. How is this motor used?: This looks like it might be a stove-hood fan motor for the type of microwave that is combined with a stove hood. If that is true, there are probably three speeds. Small fan motors are often shaded-pole motors. A shaded pole motor has only enough starting torque to start the fan it is designed for - not much torque. It could also be a permanent-split-capacitor (PSC) motor. That design has a little more starting torque, but still not MORE THAN would be needed for something like a fan or centrifugal pump. If it is that type and you don't have the capacitor, you would have virtually zero starting torque and the motor would run in whichever you give it a push to get is started. [corrected my error later] When you salvage a motor from an appliance, it is always good to look carefully to see how the wires are connected and salvage the switch and any capacitors or other external items connected to the motor. The speed is changed in this type of motor by connecting at several points on the winding to use only part or all of the stator winding. That is equivalent to running the motor on lower voltages. Operating on lower voltages weakens the motor so that the load slows the motor down. It takes less torque to run a fan at a slower speed, so the motor slows down until it find the speed at which the torque that the motor can produce matches the torque required to operate the fan.

Q:whats are elecrtric motors and where can they be used?? and how: AC motors which usually range from 110v to 4160 volts and higher are used for tones of jobs...from pumping..grinders..moving machinery..moving roller racks.. ducing electricity...etc..they also come in multiple speeds...also used for gear reducers....there are single phase....three phase...slip ring motors...variable speed motors...variable HP motors...repulsion induction motors..brake motors..and on and on DC..they are also used for varies purposes..as drive motors...shunt wound and compound wound...to drive locomotives..run various machines that require various speeds...they can also be used to produce DC electric..like generators..again i can go on and on i spent 35 yrs repairing and rewinding both AC and DC motors..i could wqrite you a small book on electric motors

Q:i got this 120 volt ac with 4 wires motor and it'll go for like 5 seconds and then it'll stop spinning for about 30 seconds and then it'll spin for 5 and the process will be repeated, any ideas on why this might be happening or how to fix it?: You have a thermal breaker in the motor. When it gets to hot it will trip and shut off. After it cools down the breaker closes and the motor starts back up. If it is heating up that fast, you have other issues, RE:too much load on the motor, bearings going, not wired correctly or maybe even the thermal breaker is weak. Most motors have a wire diagram on the plate that will indicate proper ccw or cw connections as well as the Tc or Tr which is the internal thermal breaker.

Q:What's the difference between an AC motor and a direct current motor?: The difference between AC motor with DC motor is simple and there is no difference between the brush DC motor, AC motor and the brush is no, one more than the DC inverter, DC motor brush, low noise, energy saving. The AC motor because of the frequency converter noise is relatively large, power consumption is also slightly larger. In short, each has its own advantages, according to their own use of ways to solve which to use!
