Each drive type Control and Motor is best suited for a specific application.

. Converting kW to HP. An elevator has a capacity of 2000 lbf including its own weight. The mathematical model of a DC motor.

Solid-state elevator drive is desired. Amps available on a generator per phase kva x 139. A defective generator can result in interruption or damage to productsprocesses hamper rescue operations or worst of all create serious life safety hazards.

It is important to understand the effects of regenerative type elevators for the case of a brand-new building or an existing building in which the elevators are being replaced. Read customer reviews find best sellers. The hoist motor was powered by a 15kW generator which in turn the common Ward-Leonard configuration was run by a 25-hp AC 3-phase motor.

Weight is 10000 newtons. Converting kW to kVA. Converting kVA to kW.

Im thinking of buying a generator head for it. Estimate the average power requirement in horsepower for this elevator. Size the generator to run between 60-80 full load rating of generator.

Generally geared machines are used for speeds between 01 ms and 25 ms and are suitable for loads from 5 Kg up to 50000 Kg and above. Id like to buy the 20kw model even though I only have enough hp for 15kw. A regen drive can allow the motor to essentially act as a generator creating power that also goes back to the grid.

20kva 28ampsphase over 3 phases. The AC motor was controlled by a magnetic starter with a top rating of 15 hp. Only put one on emergency power.

Overview Baldor Electric manufactures six drive types for the elevator industry. Ampere Volt-Amperes or Current I. Factor to keep voltage distortion to a reasonable level of approximately 15 total harmonic distortion THD or less.

ASDs are often thought of as being only AC drives and motors but the speed of DC motors can be easily ad - justed by voltage control and have been doing so to operate elevators for many years. The DC supply voltage from the generator is variable by changing its field current. However I dont know how much more energy it would take to turn the bigger gen head.

These Series H Controls are. Hydraulic drive for 15 kw generator. In some instances these will be the same this is the case for appliances such as TVs lights and laptops whereby the starting and running wattage is the same.

Experience suggests that AC drives can generate noise that may affect radio-frequency-sensitive equipment in the building. Large horsepower motor on the emergency generator just to allow passengers one trip to get out of the elevator. Factory calls for 30hp for 15kw and 40hp for 20kw.

My thoughts are the 20kw wont be exerted as much as 15 would be easier on duty cycle. The Ward-Leonard or motor-generator MG set Figure 4 in which a three-phase inductor motor is mechanically coupled with a DC generator. Getting the power information for your appliances.

The 28 of wasted energy plus all the other parasitics of the driving machine hydrostat charge pump hydrostat pump oil. I tried to contact with the elevator manufacturer to see whats the voltage and frequency dip that their controller can. Ad Browse discover thousands of brands.

15H Inverter 17H Vector Encoderless 18H Vector 19H DC SCR 20H DC SCR Line Regenerative 21H Inverter Line Regenerative 22H Vector Line Regenerative These Baldor Series H controls. The rotating speed of the induction motor is rather constant. With a regen drive the energy is captured and sent back to the power grid.

EMI are also addressed. Elevator often says something like 10 person limit. Ward-Leonard-style motor-generator MG sets are a form of DC drive as are silicon-con - trolled rectifier SCR-DC.

When motor is operating after start requirement will be 1kva for 1hp ie. I have a 208volt 3 phase 30 hp elevator motorwhat size feeders will I need and what size breaker to feed it. The R6 is very compact and is available in capacities.

There are two ways to have one elevator operable in the case of a power outage. Determine the running continuous watts and starting peak watts needed for each appliance. Century 15 HP Elevator Motor Motor 3 phase 1800 RPM 200 V 215T Frame ODP - R354M2.

That would be 1000kg. Specifically the elevators in question were driven by 25-hp DC motors. Factor down to 14 times the running kW of the drive.

Calculate simply as follows. Number two is a little better since if an evacuation and outage happens while the elevator in 1 is broken andor being serviced the other elevator can perform the same function. Multiply together thats 50000 watts.

20hp 20kva used when running. Speed is typically 5 metres per second. Ask Your Own Electrical Question.

1kW of generator set rating per each 34 to 1 hp of motor nameplate. 15 ton 180000 BTU a 75 x2 15 74 49 42 21 219 146 126 63 17 15 ton 180000 BTU 15 15 74 49 42 21 375 250 217 108 30 20 ton 240000 BTU a 10 x2 20 98 65 57 28 250 167 144 72 20 20 ton 240000 BTU 20 20 NA 65 57 28 500 333 289 144 40 25 ton 300000 BTU 25 25 NA 82 71 35 625 416 361 180 50. The elevator starts with an initial velocity of 0 and reaches the fifth floor just.

Heres a simple rule for estimating the size of an engine-generator set for motor starting. This is rarely done because of the poor efficiency and heat generation. Trols the speed of elevator motors.

KiloWatts 1000 watts 1 kW kW. An understanding of these phenomena is required in order to select the best possible elevator drive system for. The vertical distance between each floor is 15 ft.

With the voltage distortion created by a solid-state drive Phase C RMS Voltage Aug 15 1997 102057 300 270 240 220 200. Hello I am sizing a generator with one elevator on emergencyIts 25HP3phase208vWhen you select the load as elevator in sizing software if defaults to a voltage dip of 15 and frequency dip of 5 Hz. KEBs R6 Line regenerative drive replaces the traditional braking resistor and can be used alongside the elevator drive.

Answer 1 of 4. It can travel from the first floor to the fifth floor in 7 seconds. A pump or motor in good condition and running a reasonable speed will be 85-90 efficient so 85 x 85 72.

Whenever an empty or lightly loaded elevator goes up the motor spins but the elevators counterweight does most of the work. This design utilizes a mechanical speed reduction gear set to reduce the rpm of the drive motor input speed to suit the required speed of the drive sheave and elevator output speed. When an overhauling situation exists the R6 regen unit goes active and commutates energy back onto the building to be consumed by other loads such as lighting or HVAC.
