HySecurity MX4081, MOTOR, 60 HZ, 1PH, 5HP, 3450RPM
The HySecurity MX4081 is a 60Hz, single-phase, 5 HP, 3450 RPM replacement motor for select HySecurity / Nice HySecurity gate operator applications. This is a commercial-duty motor component intended for operators where the current parts diagram and original motor nameplate confirm the MX4081 specification.
This is not a universal gate operator motor. Matching a motor by horsepower alone is not enough. The frequency, phase, voltage, RPM, motor frame, shaft size, mounting pattern, rotation, wiring configuration, capacitor arrangement, and operator control setup all need to match before ordering.
What This Motor Does
The motor provides the rotational power used by the operator drive system. In a compatible HySecurity operator, the motor may drive a hydraulic pump, gearbox, belt, pulley, or other drive assembly depending on the operator design.
A failed or incorrectly matched motor can cause humming, slow starting, nuisance overload trips, overheating, poor gate movement, incorrect rotation, stalling under load, capacitor failure, or damage to related drive components. Because this is a 60Hz, single-phase, 5 HP motor, the site power, start circuit, run circuit, and motor protection must all be verified before replacement.
Compatible With
This motor may be used with the following applications where the current HySecurity parts diagram confirms MX4081:
- Select HySecurity gate operator applications requiring a 60Hz, single-phase, 5 HP, 3450 RPM motor
- Repairs where the original motor nameplate, parts diagram, or service documentation lists MX4081
- 60Hz power applications where the operator is configured for the correct single-phase 5 HP motor specification
- Operators where the motor frame, shaft, mounting pattern, voltage, phase, RPM, rotation, and control setup match the original MX4081 motor
- Commercial or industrial HySecurity systems where the current parts diagram confirms this motor as the correct replacement
Important: Do not assume MX4081 fits every 5 HP HySecurity operator. This motor is frequency-specific and phase-specific. Confirm the operator model, serial number, motor nameplate, incoming voltage, capacitor setup, overload protection, and HySecurity parts diagram before ordering.
Similar Parts That Are Not Interchangeable
Motor substitutions are easy to get wrong. Motors that look similar may have different frequency, phase, voltage, frame, shaft, horsepower, RPM, capacitor requirements, enclosure style, duty rating, rotation, or wiring configuration.
| Part / Motor Type | Common Description | Interchangeability Note |
| MX4081 | 60Hz, single-phase, 5 HP, 3450 RPM motor | Correct where MX4081 is listed by the current HySecurity parts diagram |
| MX4080 | 50Hz, 3-phase, 5 HP, 3000 RPM motor | Not the same as MX4081; different frequency, phase, and RPM |
| 3-phase 5 HP motor | Motor designed for 3-phase power | Not a substitute for this single-phase motor unless HySecurity confirms a full approved conversion |
| 50Hz motor | Motor designed for 50Hz power | Not automatically interchangeable with a 60Hz motor; speed, torque, voltage, and control setup must be verified |
| Lower horsepower motor | 3 HP or smaller replacement motor | Not a substitute for a 5 HP application unless HySecurity documentation specifically approves it |
Not Intended For
- 50Hz operator applications requiring a different motor
- 3-phase gate operator applications
- Operators requiring a different horsepower rating
- Operators requiring a different RPM, frame, shaft, voltage, or mounting pattern
- DC motor applications
- Small residential gate operators or light-duty systems
- General industrial motor replacement without confirming the HySecurity operator parts diagram
- Bypassing capacitors, overloads, contactors, fuses, disconnects, controller protections, limits, or safety devices
Important Compatibility Warning
The MX4081 motor is a 60Hz, single-phase, 5 HP, 3450 RPM motor. Do not replace it with a 3-phase motor, 50Hz motor, smaller HP motor, or different RPM motor unless HySecurity documentation specifically confirms the substitution.
Single-phase motors may rely on start and run circuits, capacitor values, centrifugal switches or internal switching, and correct overload protection. If those related components are incorrect, worn, or damaged, a new motor may hum, fail to start, overheat, or trip protection devices even when the replacement motor is correct.

Technician Note
Before replacing the MX4081 motor, confirm why the original motor failed. Single-phase motor problems are often caused by failed start or run capacitors, incorrect voltage, loose terminals, bad contactor contacts, improper overload protection, water intrusion, a locked pump, seized gearbox, gate binding, or an overloaded drive system.
Check the motor nameplate against the operator wiring diagram before installation. Rotation direction, wiring configuration, capacitor values, overload settings, and incoming power must be correct. A 5 HP single-phase motor can be damaged quickly if it is trying to start against a seized drive system or if the start circuit is not working correctly.
Before Ordering, Confirm
- The original or required part number is MX4081.
- The motor required is 60Hz, single-phase, 5 HP, 3450 RPM.
- The operator model and serial number match a HySecurity parts diagram that lists MX4081.
- The incoming voltage matches the motor and operator configuration.
- The operator is not a 50Hz, 3-phase, or DC application requiring a different motor.
- The motor frame, shaft, mounting pattern, rotation, and wiring configuration match the original motor.
- The start capacitor, run capacitor, overload, fuses, disconnect, and controller outputs are rated and functioning correctly.
- The driven load is not seized, binding, or mechanically overloaded.
- The package contents include only what is needed, or related mounting and drive components are being ordered separately.
Installation and Service Notes
- Disconnect and lock out power before servicing the motor or operator wiring.
- Verify incoming voltage before energizing the replacement motor.
- Confirm the correct capacitor values and wiring arrangement where capacitors are used.
- Set motor overload protection according to the motor nameplate and operator requirements.
- Confirm rotation direction before returning the operator to service.
- Inspect motor mounting, couplers, belts, pulleys, gearboxes, pump connections, and alignment before startup.
- Do not force the motor to run if the gate, gearbox, pump, or drive system is binding.
- After installation, test full travel, load operation, motor temperature, overload behavior, and all required safety devices.
Professional Advisory
This is a high-voltage, single-phase 5 HP motor component. Installation and troubleshooting should be performed by a qualified gate technician or electrician familiar with commercial gate operators, motor capacitors, overload protection, and HySecurity control systems.
Do not bypass capacitors, overloads, fuses, disconnects, contactors, controller protections, limits, safety devices, or entrapment protection to keep the operator running. If the motor is overheating, humming, tripping overloads, running backward, or struggling under load, the system should be inspected before continued use.
