Description

An electric actuator is basically a geared motor. The motor can be of various voltages and is the primary torque-generating component. To prevent heat damage from overwork or excessive current draw, electric actuator motors are usually equipped with a thermal overload sensor embedded in the motor windings. This sensor is wired in series with the power source and opens the circuit should the motor be overheated, then closes the circuit when the motor reaches a safe operating temperature.
An electric motor consists of an armature, an electrical winding, and a gear train. When power is supplied to the winding, a magnetic field is generated causing the armature to rotate. The armature will rotate as long as there is power to the windings when the power is cut, the motor stops. Standard end of travel limit switches, which are a necessity for an electric actuator handle this task.

Features and Benefits

• Motor: Reversing, brushless, capacitor run 115 VAC 50/60 Hz, single phase
• RoHS Compliant
• UL-508 Approved
• Overload protection: Integral thermal overload protection for motor windings with automatic reset
• Gear train: Permanently lubricated, solid gear that is Rockwell hardened
• Corrosion resistant housing: Thermally bonded baked powder coating with stainless steel trim
• ISO mounting configuration
• Conduit: Two 1/2" NPT conduit entries to eliminate cross feed between control, feedback, and power signals
• Position indication: Highly visible beacon position indicator for positive position of valve, even at a distance
• Declutchable manual override: Pull up on indicator knob, insert 5/8" wrench onto flats and rotate in the appropriate direction (CCW for open, CW for close). Models with handwheel override do not require a wrench. Simply push down on handwheel until engaged with cam and rotate
• Limit switches: Standard end of travel limit switches can be used for light indication (not to be use with PLC for position confirmation)
• Enclosure: Combination NEMA 4X, 7 & 9 enclosure for use in various environments
• Corrosion resistant mounting: Mounting is with PPG or stainless steel bracket, stainless steel coupling, and stainless steel hardware
• CE compliant motor: All 115 VAC and 230 VAC motors are CE compliant and stamped as such
• Extended duty cycles: Our extended duty cycles are ideal for modulating and high cycling applications
• Output torque: Series 92 Electric Actuators have an output torque range from 400 in/lbs to 2000 in/lbs
