NISHISHIBA M-G Set Voltage/Frequency Converter
Advanced Equipment supported by High Technology
Nishishiba M-G set is the Best Power Supply for the Product Inspection because of the Output Voltage Wave Form is extremely near the Sine Wave compared with the Inverter.
Nishishiba M-G set is environment friendly because of the Nitrogen Oxide free and the Carbon Dioxide free compared with Engine Generators.
Synchronous Motor - Synchronous Generator M-G Set
1. The Synchronous Motor supplies Constant Frequency Power. Voltage is variable.
2. Both Motor and Generator are very easy to maintain because of Brushless Type.
Typical Use of Synchronous Motor - Synchronous Generator Type
- 60Hz Power is necessary in the 50Hz Commercial Power District. (Constant Voltage) Or its reverse case.
- (Ex: Power for Vessel mooring or under construction in the 50Hz District)
- Constant Voltage is necessary that is different from
Commercial Power Voltage. (Constant Frequency)
- (Ex: Testing Power for Motor)
- Wide Range Voltage is necessary. (Constant Frequency)
- (Ex: Testing Power for many kind of Motor)
- Combination of Item 1 and Item 2
- (Ex: Power for Vessel mooring over seas)
Note: Unless little Frequency Variation does not affect the Test Result, Induction Motor can be applied.
Induction Motor - Synchronous Generator M-G Set
1. Output Frequency is changed freely by the Speed Control for Induction Motor. Also Voltage is variable.
2. Both Motor and Generator are very easy to maintain because of Brushless Type.
Typical Use of Induction Motor - Synchronous Generator Type
- Constant Frequency Power is necessary that is different from Commercial Power Frequency. (Constant Voltage)
- (Ex: Specified Frequency Testing Power)
- Wide Range Frequency is necessary. (Constant Voltage)
- (Ex: Alternative Power Supply to Inverter)
- Combination of Item 1 and Item 2
- (Ex: Testing Power for Motor)
