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: My electric motor will not come on each time. I turn the ac on. especially when it has been cool over night. After driving a while it may come if I have had air coming thur the vent
- You may have a faulty temperature sensor. Have it checked by a licensed mechanic.
- Q: Want to run for display. Very slow variable control so people can see operation clearly. Similar to a treadmill circuit but much lower HP. Would like control like rheostat for demonstration. DC motor preferred with transformer. Trying to keep cost at a minimum for the museum.
- or if there are any manufacturing plants near you, someone might be ripping one out [or reducing spares inventory] and you could get it free.
- Q: its wired to go cw but either way you wire it ,the motor change direction each time it stops
- your need your capacitor in your fan check !
- Q: Details too ?
- will answer it better than anyone here most likely
- Q: Expansive speed control Not able to operate at low speed Are there anymore Disadvantages?
- Speed Control The main disadvantage of AC motors, when compared with DC motors, is that their speed is more difficult to control. AC motors can be equipped with variable frequency drives, which provide smooth turning moment, or torque, at low speeds and complete control over the speed of the motor up to its rated value. Variable frequency drives improve speed control, but do create losses with reduced power quality. Control Complexity The device used to control an AC motor, known as an AC drive, is typically more complex than that used to control a DC motor. An AC motor controller must convert AC mains electricity to DC, and convert DC back again to an adjustable frequency and voltage output to the AC motor. By contrast, a DC motor has a separate field, or excitation, and power circuits, requiring just a single power conversion from AC to DC -- so the circuitry of a DC motor controller is simpler. Power Torque Historically, another disadvantage of AC motors has been that they develop less power, or less torque, per frame size. Research conducted by Rockwell Automation compared typical, commercial AC and DC motors in industry standard National Electrical Manufacturers Association (NEMA) frame sizes, and found this to be the case. However, AC and DC motors employ different classes of insulation and have different service factors -- the overload capacity at which the motor can operate without damage -- so direct comparison is not always straightforward. Other Disadvantages AC motors are typically more expensive than DC motors for most horsepower ratings. If the rotor of an AC motor rotates faster than the speed command of the AC drive, the motor acts as a generator and pumps, or regenerates, energy into the drive. If the drive cannot absorb this energy, the drive will switch off, or trip, with a fault. AC drives capable of regeneration are more complex and more expensive than DC regenerative drives. AC motors may also produce more audible noise than DC motors.
- 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.
- If it is made for electric cars, they will make controllers for them. For some reason, I think you are trying to use a motor made for fixed industrial equipment, not to move a car.
- Q: Or how do I find out? I've been trying my hand at some simple woodworking and I like it. I want a small lathe but don't really want to spend the money on one. I have an old vacuum cleaner that hasn't been used in a long time and I ripped the motor out of it. I'm planning on using this along with maybe some old bicycle wheels or maybe some roller skate bearings to make a small little lathe but I don't know if it turns enough rpms.
- There's no way a motor in a vacuum cleaner is going to have the horsepower or torque to turn a lathe. It doesn't have to do with RPMS (in fact, a lathe is going to spin slower than a vacuum cleaner), but with power. I wouldn't go with anything less than 1/2 HP for a lathe, and a vacuum cleaner isn't anywhere near that.
- Q: the motor for heat or AC
- It comes out from the bottom rt. hand corner of the HAVIC unit box. There should be ,if memory serves me, 5- 5/16 head screws going in from the bottom around the blower motor unit. The hardest one is in the corner.
- Q: i have 380/480volts 50-60 hz 7.5 kw 3 phase AC motor pump. my power supply is only 208 vac. while running it gives only 19 amps for each phase, but the motor is very very hot.
- you are using the 'extra'' legg off the transformer to get the 208 volts. why? the motor takes 3 hot leggs not 2. Get an electrician to wire it correctly.
- Q: I have this saw and the speed control board has gone bad,so i am going to try and use a variable ac or dc power supply to run the saw,but i am not sure which one the motor uses. I have already hooked the motor to a battery charger,it ran find but does not have enough torque for the blade to cut wood.
- It is ac. If you understand how motors work, you would see that dc will turn ac motors, but it wont run it effectivly.
