Motor Units

Science / Biology / Motor Units: Consist of a motor neuron with a group of muscle fibers; form the units into which skeletal muscles are organized; enable muscles to contract on a graded basis.

Polyphase Motor

Technology / Motors / Polyphase Motor: Two or three-phase induction motors have their windings, one for each phase, evenly divided by the same number of electrical degrees. Reversal of the two-phase motor is accomplished by reversing the c MORE

Part Winding Start Motor

Technology / Motors / Part Winding Start Motor: Is arranged for starting by first energizing part of the primary winding and subsequently energizing the remainder of this winding in one or more steps. The purpose is to reduce the initial value of t MORE

Parked Motorcycle Syndrome (PMS)

Technology / Motorcycle / Parked Motorcycle Syndrome (PMS): PMS is defined as Parked Motorcycle Syndrome. This is a common disease that occurs in the winter when a rider is unable to take his/her motorcycle out for a ride and is forced to think about things ot MORE

Practical Salinity Units (PSU)

Science / Marine Biology / Practical Salinity Units (PSU): A measure of the salt content of seawater (practical salinity), based upon electrical conductivity of a sample relative to a reference standard of sea water, which now happens to be a reference set of MORE

Psychomotor Agitation

Science / Psychiatry / Psychomotor Agitation: Excessive motor activity associated with a feeling of inner tension. When severe, agitation may involve shouting and loud complaining. The activity is usually nonproductive and repetitious, and consis MORE

Reluctance Synchronous Motor

Technology / Motors / Reluctance Synchronous Motor: A synchronous motor with a special rotor design which directly lines the rotor up with the rotating magnetic field of the stator, allowing for no slip under load. The reluctance motors have lower effi MORE
