Permanent magnet alternator (PMA) Precilec
PMA PMG RADIO ENERGIE®

ADVANTAGES OF THE PILOT GENERATOR
Excitation systems of generators including a pilot generator have a more simple and more rational design than the compound excitation systems and provide to the set a larger reliability

DESIGN OF THE PILOT GENERATOR
Magnets : Samarium Cobalt - very stable, high coercive magnetic field
Stability of the voltage in process of time
Stability of the voltage afler a short-circuit
Dismantling without voltage loss : no irreversible demagnetisation
Large number of solutions : pole number, size for the machines
Supplying of the required power to the regulator under any condition of the running of the main generator

MECHANICAL CHARACTERISTICS
Frame, endshields : aluminium, cast iron or steel according the solutions·
Machine with bearings
Mounting : IM 1001 or 3001 or 3601 (low shaft height)
Floating mounting or
Rotor / Stator fitted inside the frame or outside the main generator
Cooling : IC 00, IC 01, IC 0041 or IC 0141
Protection : IP 00, IP 23, IP 44 or IP 55
Insulation class F
Temperature rise class F or B : 100 K or 80 K
Ambient temperature : 40°C or others
According to the required speeds and mounting modes
(Rotor/Stator) : binding of the rotors (magnets) : either metallic or carbon fibre
