60-50 Hz Frequency Conversion
Horlick 50SC, 50RG and 50SH Model motor-generator sets provide 60-50 Hz frequency conversion for export manufacturers and military installations worldwide. There are a few elementary differences between these units which includes the motor design, mechanical drive system, output frequency tolerance and power capacity. While all three models can be used in virtually any 60-50 Hz application, they each have unique characteristics which make them best suited for specific applications.
50SC Model Motor-Generator
Belt-Driven, 5 to 313 KVA
Horlick 50SC Model motor-generators represent our most economical 60-50 Hz package. They are most commonly used in industrial applications. These units utilize a 4-pole, 1800 RPM, induction motor to drive a 4-pole, 1500 RPM synchronous generator through a V-belt drive system. The output frequency is 50 Hz (+/-1.5%) due to slip of the induction motor. Horlick 50SC Model units are offered in capacities ranging from 5 to 313 KVA.
50RG Model Motor-Generator
Reduction Gear, 375 to 1250 KVA, for Higher Power Range
For standard applications requiring a power capacity greater than 313 KVA, Horlick 50RG motor-generators are recommended. These systems utilize a 4-pole, 1800 RPM, induction motor to drive a 4-pole, 1500 RPM synchronous generator through a reduction gear drive system. The output frequency is 50 Hz (+/-0.5%) due to slip of the induction motor. Horlick 50RG Model units are offered in capacities ranging from 375 to 1250 KVA.
50SH Model Motor-Generator
For Specialized Military or Industrial Applications
Horlick 50SH Model motor-generator sets are reserved for specialized applications. These units utilize a design in which a 12-pole, synchronous motor and a 10-pole, synchronous generator are placed on a shaft that rotates at 600 RPM. The output frequency of this unit is precisely 50 Hz given an accurate 60 Hz input. 50SH Model systems are inherently quiet and they are offered in capacities ranging from 25 to 2000 KVA. They are typically only deployed in military applications with harsh environmental conditions or in industrial applications with very large power requirements. They are not typically utilized in industrial facilities requiring less than 313 KVA of power.
Horlick 60-50 Hz motor-generator sets are equipped with a standard control system that can be unit-mounted, wall-mounted or free standing. The components in the control system perform the functions necessary to operate, monitor and protect the units. We offer a number of custom options with our motor-generator sets to include mounting them in a weather-resistant enclosure, in a sound-reduced enclosure or on a trailer. Along with this, we offer control panel options to include PLC control with Operator Interface Terminal, generator reconnection switch, or digital meter package as a minimum.
