IntroductionThis guide provides IQ motor data for standard class F, 15 minute rated actuators at the following supply voltages:

60HZ 200 208 220 230 240 380 440 460 480 575 600

50Hz 200 220 240 380 400 415 440 460 500 525 550 660 690

Important Notes� At any voltage, “apply” indicates that the particular motor has not been systemised. Contact Rotork.� IQ 90 at 48 rpm and higher speeds are not available at voltages up to and including 240V� IQ91 is not available at 60Hz voltages below 440.� IQ91 is not available 50Hz voltages below 380.

Glossary� Rated Torque – Corresponds to 100% torque switch setting� Locked Rotor – motor starting and stalled condition� Rated Amps – current at 100% torque switch setting� Average (nominal) load.-. Corresponds to 33% of rated torque. This average value has been confirmed as conservative after 40 years of experience in valve motorisation. It encompasses low torque values around the open position with rising torque as flow throttling takes place to final seating torque.� Efficiency – electrical efficiency of the actuator motor.

Design criteriaMotors designed for operation of valve actuators require special consideration. As continuous running is not a requirement with isolating and “inching” or regulating duty valves, motors need only be short duty time rated. Valve load can vary dramatically across stroke and from stroke to stroke as process and valve conditions vary. Varying from light running to rated torque with a facility to exceed rated in unseating “sticky” valves, actual motor loading has no constant. To apply traditional motor protection to actuator motors is therefore flawed, leading to spurious tripping or no protection at all.

Rotork recognise the special nature of actuator motors and have therefore designed the IQ motor and its control package with this unique duty at the forefront.

IQ Motor DesignIQ motors are of a low inertia, squirrel cage induction design, reaching full speed in 3 cycles of the mains frequency. In their standard 3 phase form they are class F insulated, rated 15 minutes at average load. The motor torque/speed characteristic has been designed to fulfil the following requirements:� High stall torque in comparison with that required to operate and seat the valve. This is essential in maintaining rated torque at depressed voltage conditions as torque varies with the square of the voltage. Rotork are able to guarantee actuator performance at –10% of nominal voltage.� Pull out torque available at speed (50-70% of synchronous) which combined with the lost motion drive, allows the motor to reach full speed with maximum available torque before the drive is applied to the valve, ensuring unseating for all except jammed valves. For “inching” duty when the lost motion has been taken up, starting torque is high, at least 80% of pull out torque.

IQ motor control protectionThe primary protection for the motor is torque switch protection. By measuring the actuator output torque and comparing to the open and close torque switch setting, effective motor and more importantly, valve protection is achieved. IQ motors are also protected by two thermostats embedded in the motor end windings providing over temperature protection if the duty cycle exceeds actuator rating. IQ control protection will prevent motor stall in the event of valve jamming *. Phase rotation protection and lost phase protection are also incorporated as standard.

Using torque as the primary means of motor protection along with thermostat and IQ control protection eliminates the requirement for traditional protection methods and their inherent weakness when applied to short time duty, variable load motors.

*If “Boost” open torque is set the actuator will develop torque in excess of rated and can stall in attempting to unseat a jammed valve. If the actuator stalls, jammed valve protection will trip the motor within 4 seconds.

Power supply cable sizingAs a minimum requirement, cables must be sized to ensure volt drop does not exceed 15% of nominal supply voltage at locked rotor current.

Fuse selection Due to the unique nature of the motor duty and taking in to account the comprehensive control protection of the IQ, sizing of fuses or trip devices should be based on protecting the power cable connected to the actuator.

If required, protection may be enhanced by sizing trip devices to disconnect after 10 seconds at locked rotor current. This will reduce the risk of severe motor heating under stall conditions while preventing spurious trips under normal operation. It should be noted that sizing trip devices in this manner may not be possible while meeting other criteria and is purely designed to meet extreme fault conditions such as jammed contactor when standard control protection cannot de-energise the motor. All other operating conditions will be catered for by the standard IQ control protection.

Frequency converters and UPSFrequency converters for variable speed drives are not recommended as a suitable supply for IQ actuators. Where UPS systems are required, the power supply should have negligible harmonic distortion. In general terms actuators are designed to operate on power supplies conforming to recognised power supply standards such as EN 50160 – Voltage Characteristics of Electricity Supplied by Public Distribution systems. Please apply to Rotork with specific UPS supply characteristics if different from above.

Motor OptionsIQ motors are available with extended duty cycles and Class H insulation. Please apply.
