The components of the insulation system are selected to ensure food protection. All meterials used for insulating the winding and winding ends correspond to insulating class F or H according to IEC standard.
The following defines the insulation class per IEC 60034-1 with max 40°C ambient temperature.
Standard Yamanashi-Denki motors are rated Class F with Class B temperature rise for single speed continuous duty, S1 condition.
Y2 series
Voltage and Frequency
The operating voltage and frequency has variation of + / - 5% can be accommondated with some de-rated performance as a consequence.
Yamanashi-Denki motors are suitable for DOL starting.
Motors up to 3kW are Star connected. Motors 4kW and above are Delta connected with 6 terminals for Star-Delta starting. In medium to large motors, the Star-Delta connection is more common for it can reduce the starting current by about 30%
Rated Voltage           :  3kW and below: 230 / 400V, 3 phase
:  4kW and above: 400 / 690V, 3 phase
Rated frequency      :50 Hz(Standard), 60 Hz(Optional)
