Explain the relationships among speed, frequency, and the number of poles in a three-phase induction motor

Business
1 answer:
Triss [41]3 years ago
5 0

The synchronous speed (rpm) equals 60 times the frequency divided by the number of pole pairs. For 50Hz, a two-pole motor will have a synchronous speed of 3000 rpm, a four-pole motor of 1500 rpm.

The actual speed is a few percent lower due to the slip of the asynchronous motor.


The slip increases with the torque, typical values are 5–10%. The rated speed for a four-pole motor at 50Hz will thus be something like 1360 rpm. At no-load, the slip is very small.

MrRissso [65]

Answer:

$118,220

Explanation:

The Costs of Goods Sold COGS is calculated using the following formula.

COGS = Beginning inventory + purchases - Ending Inventory

For Azur company

Beginning inventory:  30,840

Ending inventory : 20,560

Net purchases equal Net purchase equal to purchases plus freight-in minus discounts  freight-out are administrative expenses, hence do not feature in COGS

Net purchases =$102,800 + $15,420 -$ 10,280

Net purchases =$107,940

COGS = $30,840 +$107,940 -$20560

COGS = $118,220

Which one of the following is not an assumption of the EOQ model? Decisions for one item can be made independently of decisions
irga5000 [103]

Answer:

Quantity discounts can be taken advantage of for large lot sizes.

Explanation:

The EOQ model assumptions:

the order of one item does not intervene with the other.

The order will arrive without delay and with a specific amount of goods.

no losses or damage in transit

The EOQ does not consider the discount for large lot size, their formula does not consider the value of the goods:

Q_{opt} = \sqrt{\frac{2DS}{H}}

Its use: Demand of the good

cost of Setup, or ordering cost.

and Holding cost, the cost of keeping the inventory

There is no variable to account for discounts for order size in this method

DiKsa [7]

Answer:

A) They would be indifferent, as Sally's income net of costs equals $25,000.

Explanation:

Sally's economic profit = accounting profit - opportunity costs

  • accounting profit = $12,000
  • opportunity costs = $25,000 - $15,000 in lost salaries + $2,000 (lost investment revenue) = $12,000

economic profit = $12,000 - $12,000 = $0

Since the economic profit is $0, Sally should be indifferent between running her own business or working for someone else.
