2014-12-8 Amplitude = 4 to 5 mm. Speed = 1000 rpm. Weight of feeder including vibrator = 3000 kg (approx) max. feed size of material = 600 mm. amplitude = static moment /wt of structure including vibrator. so static moment = 4 mm x 3000 kg =1200 kg.cm. I am going to use two vibrator for getting linear motion.

2014-2-2 Bit of a Drag. 'Drag chain' could refer to a reclaimer; scraper chain conveyor; apron feeder etc. Each has its own particular drag force. Selected chain speed determines rpm and motor power is chain speed x drag but usually factored according to the drive duty. Maybe it doesn't help much: but neither does the question.

2022-1-11 Calculate the total power consumption of the 3 Phase 30HP motor is operating for 38 days at 70% of the full load and the motor is operated at 14 hours per day. Step1: First calculate the total number of hours. T (h) = 38 * 14 = 532 hours. Use our power calculation formula, E (kWh) = 0.746 * 30 * 532 * 0.7 = 8334 kWh.

2012-1-30 An electric motor’s nameplate or rated power is its output power, not its electric input power. Electric power consumption is rated power divided by motor efficiency. Rated power depends on class of motor (which considers intended duty). Industrial grade motors usually are rated for continuous duty.

Milling Horsepower Calculator. Calculate the horsepower required for a milling operation based on the feed rate and depth of cut, which are used to determine the material removal rate (or metal removal rate). Also required is the unit power, which is a material property describing the amount of power required to cut that material.

2004-5-1 Remember, motor feeder conductors must be protected against the overcurrent that results from short circuits and ground faults but not those that result from motor overload. When sizing the feeder protection, be sure to include only the motors that are on the same phase. Refer to Fig. 5 for this sample motor feeder protection calculation.

The highest rated motor is the motor with the highest FLC [430.17]. Determine the “other motors in the group” value by balancing the motor FLCs on the feeder being sized, then select the line that has the highest rated motor on it (Fig. 2 on page 78). Branch-circuit short-circuit and ground-fault protection.
