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: I can find plenty of stuff online about electric motor assembly, but I want to know how the parts are actually made and what they are usually made from. It's for a report for college so quite urgent. I'm assuming they're cast somehow or something. All help appreciated!
- They are made in factories designed for that purpose. The parts are things like laminated steel, enameled copper wire, commutators, brushes, shafts (steel), springs, cast iron cases, bearings. All are made separately, and the description of how each are made would take a book. Try looking each up on the internet. And the parts and processes can vary a lot with the size and type of motor.
- Q: My dad owns this car and the AC recently went out and he does not have accessibility to information regarding how to replace the blower motor. Has anyone done this, or do you have access to detailed instructions from Chilton's, etc.? I tried to look online, but I came up empty-handed. My dad used to own an auto repair shop, so do not worry about your response being too detailed or technical. Any assistance would be greatly appreciated. Thank you in advance.
- discover the blower motor and unplug the electric connection. clean any rust from the area and reconnect. that could shelter it. I purely did that with my daughter's chevrolet final month here in Michigan. If it makes an unusual noise like a screech, that usually shows the around plastic piece that the motor turns is wiped out and desires changing. That expenses approximately $20.
- Q: How is frequency is efecting when a motor running by electric power,What is the relation of KW with FREQUENCY?
- Dear Meetantacheri, I am not sure which frequency you refer to: 1) The Power Supply Frequency You need to look in your Ordinary Level Physics Books or on the wwweb at: Synchronous AC Motors Asynchronous AC Motors 2) The Rotational Speed of the Motor: For a DC Motor this depends on whether the rotor and stator are Series or Parallel Connected and the Mechanical Load that is on the Motor. For a Synchronous AC Motor you get field slippage if the mechanical load is too high I am not sure what you mean by the kW / f part. If a motor is overloaded it slows down, takes a lot of current and the power consumption rises. This overheats the motor and the winding are destroyed. (see back-EMF)
- Q: Does a 1 HP motor draw more wattage than an AC one at the same EMF?
- 1 HP is 746 watts. It doesn't matter if it is a 120vac motor or a 240vac motor. A 120vac motor will draw 2x the current than a 240vac motor to develop the same HP. A 1 HP, 120v DC motor still draws 746 watts. But a DC motor can't run on AC power, nor can and AC motor run on DC power without some sort of inverter or converter. The matter of efficiency is something else. Some of that power used to develop 1 HP is lost to friction or heat.
- Q: Is suppression capacitor (Volt AC) can be used as motor starting capacitor?
- I wouldn't try it. Capacitors have a maximum ripple current rating. The EMI cap doesn't have as high a rating as an oil filled motor start capacitor.
- Q: The Pump Motor Hums when the switch is turned on. Remove the pump and the impeller turns freely.
- impeller is shot
- Q: as an alternative I want to generate electricity domestically at my home. I want to use simple motor as a generator. Instead of giving supply to motor I with attach a propeller to motor shaft and drive it.
- Yes you can but 1.your properller speed should be little more than the RPM specified in the motor's name plate. 2.You may have to use some voltage stabilizers
- Q: I know its been asked before but I need advice on what kind of motor to use for making a rotisserie. I want to be able to add a potentiometer and have a speed of between 2 and 10 RPM. I was originally thinking of a washing machine motor but think that it may not have the power at lower speeds.I Would also like to do it with a direct drive instead of having loads of pulleys as featured on you tube, although i realize some gearing may be required.Thanks in advice people.
- The best suitable motor would be a DC motor. You can get a 12 V DC motor powerful enough for a rotisserie. But a gearbox is a must for the required speeds.
- Q: A 3 phase, 2 hp, 480 volt AC motor online? (case/price doesn't matter)
- pls visit www.electricity.uk for for knowing all bout engineering
- Q: and some formulas for calculating electric motor speed
- AC motors usually have the following on the nameplate: Rated output power – Pr (kilowatts – kW or Horsepower – Hp) Rated speed – nr (revolutions per minute – RPM) Rated voltage – Vr (volts – V) Rated frequency – fr (hertz – Hz) Rated current – Ir (amperes – A) Other parameters (not on the nameplate): Rated torque – Mr (Newton meters – Nm or pounds feet – lbs-ft) Mr=9550xPr/nr for Mr in Nm Pr in kW Mr=5252xPr/nr for Mr in Hp Pr in lbs-ft Number of poles – p (always an even number, only north/south pairs are possible) With 3-phase induction motors, speed can be increased or decreased by changing the frequency: Speed, n = 120f/p To have available torque remain constant at M = Mr without current exceeding rated current, voltage must be increased or decreased with frequency change such that V = f x Vr/fr. Speed increase is limited by the motor’s ability to tolerate the electrical stress due to increased voltage and the mechanical stress due to increased speed above the rated values. If the frequency is increased above the rated value without increasing the voltage, the available torque will be reduced. Up to about 50% above rated speed, the available torque is approximately the torque that will produce the rated output power. Under some load conditions, some types of single phase motors can be controlled in the same way to a more limited extent. Under some load conditions, with some types of single phase and three phase motors voltage reduction can be used to reduce speed to a limited extent.
