Why is the efficiency of an induction motor (wound rotor) so poor at high at slips?
The efficiency of a wound rotor induction motor decreases at high slip because, at higher slips, the rotor experiences greater relative motion between the rotating magnetic field and the rotor, leading to increased rotor currents and losses. This results in higher copper losses due to increased current flowing through the rotor windings. Additionally, the increased slip causes a reduction in the motor's output torque and power factor, further contributing to overall inefficiency. Consequently, as slip increases, more energy is lost as heat, reducing the motor's overall efficiency.

What is the difference between synchronous motor vs induction motor and which one is better?
The big difference is that the synchronous motor's rotor can have a variable current applied to it through its field slip rings. Both types of motors have their own advantages. With a synchronous motor in the system, the systems power factor can be regulated.
What are drill pipe slips used for?
Drill pipe slips are used in drilling operations to securely hold the drill pipe in place while making connections or during tripping operations. They are designed to grip the pipe without damaging it, allowing for safe handling and preventing the pipe from falling or slipping during operation. By providing a stable support point, slips facilitate the efficient and safe management of the drilling process.
What are drill pipe slips?
Drill pipe slips are specialized mechanical devices used in drilling operations to secure and support the weight of the drill string when it is being lifted or lowered into the wellbore. They are typically made of metal and feature serrated teeth that grip the drill pipe, preventing it from slipping or falling. Slips are essential during tripping operations to ensure safety and maintain control over the drill string. They are usually part of the drilling rig's rotary table or a similar assembly.

Driver side electric window slips and won't go up or down How do you get to the gear?
If your window slips, make sure it is "on the track". If it is, then check the motor. They are easily found in pick a part yards.
How helicopter go up?
The rotors on a helicopter are slanted and shaped so that when the rotors spin air slips right under the rotor and get pushed down therefore creating lift.
Evinrude 25 horsepower outboard prop slips while under a load. Or could it be cavitation?
Sometimes the center of the prop breaks loose and slips or the splines get stripped. Also check to make sure you have the correct pitch prop for that motor and it is fastened securely.
What is slip system?
In this system, posting is made from slips prepared inside the organization itself or from slips filled in by its customers. So entries are not made in the books of original entry or subsidiary books, but posting of entries is done from slips. In a banking company, the main slips are pay-in-slips, withdrawal slips and cheques and all these slips are filled in by clients of the bank. These slips serve the basis of entry in the ledgers and control accounts in the General Ledger are prepared on the basis of analysis of these slips
