HySecurity MX001645, MOTOR ASSY, 2 HP,3PH,50HZ, 2850
The HySecurity MX001645 is a 2 HP, three-phase, 50Hz motor assembly rated at 2850 RPM for select HySecurity / Nice HySecurity gate operator applications. This motor assembly should be used only where the current HySecurity parts diagram, motor nameplate, and operator configuration confirm MX001645 as the correct replacement.
This is not a universal gate operator motor. Matching by horsepower alone is not enough. The phase, frequency, RPM, voltage, frame, shaft, mounting pattern, rotation, wiring layout, overload protection, and operator drive arrangement all need to match the original motor assembly.
What This Motor Assembly Does
The motor assembly provides the rotational power used by the gate operator drive system. Depending on the operator design, the motor may drive a hydraulic pump, gearbox, belt, pulley, drive wheel, or other mechanical drive component.
A failed or incorrectly matched motor assembly can cause humming, tripped overloads, overheating, incorrect rotation, slow movement, stalling under load, nuisance fuse failures, or damage to related drive components. Because MX001645 is a 50Hz, three-phase motor assembly, the incoming power and operator control setup must be verified before replacement.
Compatible With
This motor assembly may be used with the following applications where the current HySecurity parts diagram confirms MX001645:
- Select HySecurity gate operator applications requiring a 2 HP, three-phase, 50Hz, 2850 RPM motor assembly
- Repairs where the original motor nameplate, parts diagram, or service documentation lists MX001645
- 50Hz electrical supply applications where the operator is configured for the correct three-phase 2 HP motor assembly
- Operators where the motor frame, shaft, mounting pattern, voltage, phase, frequency, RPM, rotation, and control setup match the original MX001645 motor assembly
- Commercial or industrial HySecurity systems where the current parts diagram confirms this motor assembly as the correct replacement
Important: Do not assume MX001645 fits every 2 HP HySecurity operator. This motor assembly is frequency-specific and phase-specific. Confirm the operator model, serial number, motor nameplate, incoming power, contactor/overload setup, and HySecurity parts diagram before ordering.
Similar Parts That Are Not Interchangeable
Motor assemblies can look similar but may not be interchangeable. Horsepower, phase, frequency, voltage, RPM, shaft, frame, mounting, wiring, overload protection, and operator drive design all matter.
| Part / Motor Type | Common Description | Interchangeability Note |
| MX001645 | 2 HP, 3-phase, 50Hz, 2850 RPM motor assembly | Correct where MX001645 is listed by the current HySecurity parts diagram |
| MX001644 | 2 HP, 1-phase, 50Hz, 2850 RPM motor assembly | Related 50Hz 2 HP motor assembly, but not the same phase configuration |
| 60Hz 2 HP motor assembly | Motor assembly designed for 60Hz electrical supply | Not automatically interchangeable with a 50Hz motor assembly; speed, torque, heating, and control setup may differ |
| Single-phase motor assembly | Motor assembly for 1PH power | Not a substitute for this three-phase motor assembly unless HySecurity confirms a complete approved conversion |
| Different HP or RPM motor | Motor with different horsepower or speed rating | May change load capacity, operator speed, current draw, and protection settings |
Not Intended For
- Single-phase gate operator applications requiring a 1PH motor assembly
- 60Hz operator applications requiring a different motor assembly
- Operators requiring a different horsepower, RPM, voltage, frame, shaft, 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 contactors, overloads, fuses, disconnects, controller protections, limits, or safety devices
Important Compatibility Warning
The MX001645 motor assembly is a 2 HP, three-phase, 50Hz, 2850 RPM assembly. Do not replace it with a single-phase motor, 60Hz motor, different horsepower motor, or different RPM motor unless HySecurity documentation specifically confirms the substitution.
Frequency and phase matter. A 50Hz motor assembly may not behave correctly on the wrong frequency or voltage, and a three-phase motor requires the proper three-phase supply, contactor arrangement, overload protection, and wiring configuration. Incorrect power can cause overheating, poor torque, incorrect speed, nuisance tripping, or motor damage.

Technician Note
Before replacing the MX001645 motor assembly, confirm why the original motor failed. Three-phase motor failures are often caused by single-phasing, incorrect voltage, wrong frequency, bad contactor contacts, loose terminals, failed overload protection, water intrusion, a seized gearbox, hydraulic pump resistance, gate binding, or an overloaded drive system.
Check the motor nameplate against the operator wiring diagram before installation. Rotation direction, wiring configuration, overload setting, and incoming three-phase power must be correct. A three-phase motor can be damaged quickly if one leg is missing, the voltage is wrong, or the driven load is mechanically locked.
Before Ordering, Confirm
- The original or required part number is MX001645.
- The motor assembly required is 2 HP, three-phase, 50Hz, 2850 RPM.
- The operator model and serial number match a HySecurity parts diagram that lists MX001645.
- The incoming power matches the motor and operator configuration.
- The operator is not a single-phase, 60Hz, DC, or different-horsepower application requiring another motor assembly.
- The motor frame, shaft, mounting pattern, rotation, and wiring configuration match the original motor.
- The contactor, 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 the complete motor assembly needed for the repair, or related mounting and drive components are being ordered separately.
Installation and Service Notes
- Disconnect and lock out power before servicing the motor assembly or operator wiring.
- Verify all three phases are present and correct before energizing the replacement motor.
- Confirm 50Hz electrical supply and the correct voltage for the operator configuration.
- 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, three-phase motor assembly. Installation and troubleshooting should be performed by a qualified gate technician or electrician familiar with commercial gate operators, three-phase power, motor overload protection, and HySecurity control systems.
Do not bypass overloads, fuses, disconnects, contactors, controller protections, limits, safety devices, or entrapment protection to keep the operator running. If the motor is overheating, single-phasing, tripping overloads, running backward, or struggling under load, the system should be inspected before continued use.

Why did my three-phase gate operator motor fail?
Common causes include single-phasing, incorrect voltage, wrong frequency, bad contactor contacts, failed overload protection, loose wiring, water intrusion, seized drive components, hydraulic pump resistance, or a gate that is binding.
Should a technician install the MX001645 motor assembly?
Yes. A 2 HP, three-phase, 50Hz motor assembly replacement should be handled by a qualified technician or electrician because the repair involves high voltage, motor protection, rotation checks, and operator safety testing.
