Permanent magnet motors consist of two main types. Surface permanent magnet motors (SPM) and internal permanent magnet (IPM) motors. The main difference is that SPM motors place the magnets on the outside of the rotor while IPM motors place their magnets inside the motor. Benefits to internal magnets include structural integrity and reducing ...
The main discussion of these abbreviations in the context of drug prescriptions and other medical prescriptions is at List of abbreviations used in medical prescriptions. Some of these abbreviations are best not used, as marked and explained here.
A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.
An electropermanent magnet or EPM is a type of permanent magnet in which the external magnetic field can be switched on or off by a pulse of electric current in a wire winding around part of the magnet. The magnet consists of two sections, one of "hard" (high coercivity) magnetic material and one of "soft" (low coercivity) material. The ...
Cancer is typically treated with surgery, radiation and sometimes chemotherapy. But a new study suggests this standard protocol might not be necessary for a common form of early-stage breast cancer.
The magneto also had a medical application for treatment of mental illness in the beginnings of electromedicine. In 1850, Duchenne de Boulogne , a French doctor, developed and manufactured a magneto with a variable outer voltage and frequency, through varying revolutions by hand or varying the inductance of the two coils, for clinical ...
The man and woman were walking along the beach at Smith Point County Park in Shirley just before 5 p.m. when they spotted the bone, police said.
The U.S. Food and Drug Administration on Monday set maximum levels for lead in baby foods like jarred fruits and vegetables, yogurts and dry cereal, part of an effort to cut young kids' exposure ...
