How many amps does a 50 hp motor draw
WebInstead of that by calculating no-load current of the 50HP motor (it will be 6 to 10 Amps), you can design low rated starting equipment (i.e starter, cables etc) to start the motor at the maintenance floor itself. The no-load current is used to improve the winding resistance (to improve the megger value). WebJan 23, 2024 · The first step to convert HP to amps is to convert HP to watts. Since 1 HP is equal to 746 W simply multiply the horsepower by 746 for this conversion. Watts = Horsepower × 746 as we know all motors are not 100 % efficient efficiency usually from 70 % to 99 %. Hence Watts = watts/ η Convert to Amps
How many amps does a 50 hp motor draw
Did you know?
WebApr 17, 2024 · Amps = HP × 746 V × η × PF Thus, the current in amps is equal to horsepower times 746 divided by the voltage times the efficiency η times the power factor. For example, let’s find the current draw in amps of a 1 horsepower motor that runs at 120 volts with a 90% efficiency. Amps = 1 HP × 746 W 120 V ×.9.

WebNov 24, 2024 · An operating three phase motor has voltages measured with a voltmeter on each phase of 453, 458, and 461 volts, amperage measured on each phase with an ammeter are 14.1, 13.9, and 13.8 amps, power factor was measured as 0.82. The average voltage is 453 plus 458 plus 461 divided by 3 which equals 457 volts.
WebJul 23, 2024 · Suppose you have a 115 HP outboard motor and a 12V battery. The amp draws for this would be: Step 1: The maximum output of your 115 Hp motor= 115 * 746 = 85790 W. Step 2: The Amp draw per hour for your motor = 85790 / 12 = 7149.167 Amp-hr. Step 3: The basic amp draw for your motor= 7149.167 / 60 = 119.153 Amp
