a) From CEM specification Section 22.31.5 request the motor provide at least 1.7 times torque between standstill and breakdown torque speed, the motor is sized per this requirement and the pump’s starting torque. b) Our proposal for extending the warranty period is to provide a confidence to use Siemens motors. c) Please refer to our reply no.10. d) To guarantee operation performance, speed limiter will be provided on the motor. e) The motor is designed to operated at 25.3Hz. The speed limited is to prevent the motors running above 505rpm (i.e. > 25.3Hz). f) Shaft-mounted fan is not suitable for VSD operation. For VSD-operated motors, its speed is varied that requires an external driven fan to cool down the motor regardless of the running speed. g) Yes, motor speed is 495rpm at 25.3Hz h) Enclosed.
