Option 4 : High starting torque

Permanent Split Capacitor motor characteristics:

  • The permanent split capacitor motor (PSC) is compact, easy to maintain, highly efficient, and has a high power factor.
  • The permanent split capacitor type motor is most widely used for 2 HP or less and for applications where starting torque requirements are 100% or less of full load.
  • The permanent split capacitor motor offers smooth acceleration and has a run winding and a start winding with a capacitor connected in series.
  • Both windings are energized when the motor is started and running. No switch is required to switch any component out of the circuit.

 

Advantages:

  • A major advantage of the PSC motor is the capability of operating at different speeds by allowing higher levels of slip.
  • Special applications include fans and blowers, air conditioners, coolers, furnaces, unit heaters, roof ventilators, dehumidifiers, garage door openers, and other applications that require low starting torque and current.

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct. 1 - One thing at least was obvious: she was not made to be looked at thus. P - The reddleman had appeared conscious of as much, and, while Mrs Yeobright looked in upon her, he cast his eyes aside with a delicacy which well became him. Q - The lips then parted with something of anticipation, something more of doubt, and her several thoughts and fractions of thoughts, as signalled by the changes on her face, were exhibited by the light to the utmost nicety. R - The sleeper apparently thought so too, for the next moment she opened her own. S - An ingenuous, transparent life was disclosed; as if the flow of her existence could be seen passing within her. 6 - She understood the scene in a moment.?

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1. Jupiter has 2.5 times more mass than all the other planets of the solar system combined and is 11 times as large as Earth in diameter. P. Jupiter is so large that scientists believe it almost became a star: as the gases and dust contracted to the form the planet, Q. But there was not enough mass available to create the temperature needed to start a fusion reaction such as that of the Sun. R. Thus, Jupiter has been cooling down ever since.  S. gravitational forces created tremendous pressure and the temperature inside the core—as high as tens of thousands of degrees. 6. Even so, Jupiter radiates about as much heat as it receives from the Sun.?
