Custom injection molded neodymium magnets

LEC magnetics has available Permanent Injection molded neodymium magnets

Injection molded magnets are used in electric motors all around us.  From the motor that spins a DVD disc to the wheels of a hybrid car, permanent magnets are used in motors everywhere.

In the electric drive motor of a hybrid car, for instance, just a kilogram, or 2.2 pounds, of neodymium-based magnets can deliver 80 horsepower, enough to move a 3,000-pound vehicle like the Toyota Prius. Neodymium is an ideal magnet material because it helps to retain a magnetic charge during all driving conditions, and when dysprosium is added to the alloy, performance at high temperatures is preserved.

While permanent-magnet motors are the most popular type used in electric and hybrid drive systems — an estimated 90 percent of today's electric vehicles use this design,— they are not the only workable design. Induction motors, for example, draw an electrical current to create the magnetic field that makes the motor's shaft rotate. Permanent magnet motors, on the other hand, rely on an existing field surrounding its magnets.For the same amount of power output, compared to an induction motor, the permanent magnet motor is always going to be smaller, lighter and more compact,Conserving battery power is important for extending the car's driving range.
