oct 08, 2019 As the pumps speed increases, the required torque gradually declines. for example, at about 15% full load speed the required torque typically is around or 10% full load torque. As shown below, the pump torque-speed curve follows the square law: overlaying torque-speed curves to match motors to pumps. like pumps, motors produce a torque .
If the motor is run outside of this curve, it will stall. slew range-the area between the pull-in and the pull-out curves, where to maintain synchronism, the motor speed must be ramped torque speed curves torque is proportional to the winding current and the number of turns of wire. To increase torque by 20%, increase .
