Technical characteristics
- Standard operating voltage and frequency: 230V/50 Hz - 400V/50
- Voltage tolerance: +5% -10%
- All the 60 Hz versions are standard with service factor as required by NEMA standard, 15% start up variant: DOL (direct on line). Direct power supply with a single power cable.
- STAR / DELTA: with two power supply cables (this type of start up should be specified at time of ordering the motor, and a starter box should be provided).
- Rotation speed: the motor is 2 yoles: whose synchronization speed is 3000 rpm for a 50 Hz network and 3600 rpm for a 60 Hz network. ( one must take into account a slippage of 2% entailing a loss of speed against thhe synchronization speed.).
- Powers: 4 KW; 5,5 KW; 7,5 KW ; 9,4 KW ; 11 KW; 15 KW ; 18,7 KW 22 KW; 30 KW; 37,5 KW.
- Coupling: flange and shaft as required by NEMA standard.
- Type de protection: IP 68.
- Insulation class: F.
- Max. ambient temperature: (external liquid) 30°C.
- Minimum external liquid speed: 0,3 m/sec.
- Max. axial thrust 16000 N.
- Mounting position: Vertical up to an angle of 30° against the horizontal.
- Start up frequency: Max. 25 start ups every hour with a max. full intensity start up time of (DOL) 3 sec.
