ELECTRIC MOTOR Sample Clauses

ELECTRIC MOTOR. Modulating actuators shall be designed for up to 1200 starts per hour and non-modulating actuators for up to 60 starts per hour. The actuator shall be fitted with a low inertia high torque electric motor. The electric motor shall have a minimum duty rating of four consecutive complete cycles or a continuous operation of 15 minutes, whichever is more onerous. The motors shall be time rated IEC 34 at a nominal motor load and at least 33% of maximum valve torque for 15 min. The motors shall be protected by thermostats embedded in the motor windings, one for each phase which shall have a facility for being overridden for emergency shutting off of the gate/valve. Each electric motor shall be fitted with a suitable reduction gearing design to unseat the gate/valve under 75% of the test pressure and to operate the valve while the water flowing through the gate/valve reaches velocities of up to 5 m/s. Refer to Particular Specification E01: Electric Motors for a detailed specification for Electric motors.

ELECTRIC MOTOR. The electric motor is warranted for five (5) years not to fail under normal conditions if maintained, operated, used, and stored in accordance with the instructions contained in the owner’s manual.
