60-400 Hz Motor-Generator Sets
Horlick 400SC and 400TR Model motor-generator sets provide 60-400 Hz frequency conversion for naval and air force bases, missile and ground support operations and manufacturers requiring 400 Hz power. These models each have a distinctly different design; however, they are both versatile enough to be utilized in virtually any 60-400 Hz application.
400SC Model Motor-Generator
Mechanically Coupled, 12.5 to 150 KVA, for Military and Industrial Applications
Horlick 400SC Model motor-generators represent our most economical 60-400 Hz package. They are utilized in industrial and military applications alike. These units consist of a 4-pole, 2000 RPM, induction motor and a 24-pole, 2000 RPM, synchronous generator mounted on a rigid steel base and connected via a flexible coupling. The motor-generator set speed is controlled by a variable frequency drive that maintains the output frequency within a frequency range of 400 Hz (+/-1%) on standard units. Horlick 400SC are offered in capacities ranging from 12.5 to 150 KVA.
400TR Model Motor-Generator
Common-Shaft, 12.5 to 375 KVA, for Specialized Applications
Horlick 400TR Model motor-generator sets are reserved for specialized applications. These units utilize a design in which a 6-pole, synchronous motor and a 40-pole, synchronous generator are placed on a shaft that rotates at 1200 RPM. The output frequency of this system is precisely 400 Hz given an accurate 60 Hz input. 400TR motor-generator sets are offered in capacities ranging from 12.5 to 375 KVA. They are most commonly deployed in demanding military environments or in applications where a precise 400 Hz output is required.
