HySecurity MX001646, Motor, Electric, 24VDC, 3/4 hp
HySecurity MX001646 is a 24VDC electric motor rated at 3/4 hp for select HySecurity DC gate operator applications. Current listings identify this part as a DC electric motor, 3/4 hp, 24VDC. Some product information also lists this motor as 1800 RPM and suitable for select B and C speed SwingRiser systems.
A HySecurity parts diagram reference also lists MX001646 as the 24VDC, 3/4 hp electric motor for StrongArm DC models. Because this motor may be used in more than one HySecurity operator family depending on configuration, do not order it by voltage and horsepower alone. Confirm the operator model, serial number, motor label, shaft/coupler arrangement, RPM, and HySecurity parts diagram before ordering.
What This Electric Motor Does
The electric motor provides the drive power for the operator's hydraulic pump or drive system, depending on the HySecurity operator family and configuration. In a DC system, the motor must match the required voltage, horsepower, RPM, shaft size, mounting arrangement, and coupler setup so the operator can run at the intended speed and load capacity.
A failed or weak motor can cause the operator to run slowly, fail to move the gate, stall under load, trip protection, overheat, or make abnormal noise. Similar symptoms can also be caused by low DC supply voltage, weak batteries, controller output problems, loose wiring, a bad contactor or relay, a damaged motor coupler, hydraulic pump problems, hydraulic pressure issues, gate binding, or mechanical drag.
Compatible With
Use HySecurity MX001646 only where the operator parts diagram, original motor label, or HySecurity documentation confirms this part number.

Possible Operator Family Use
Based on current product and parts-diagram information, MX001646 may be associated with more than one HySecurity operator family. Always verify the exact parts diagram before ordering.
- HySecurity SwingRiser B speed systems where the parts diagram lists MX001646.
- HySecurity SwingRiser C speed systems where the parts diagram lists MX001646.

Important Compatibility Warning
MX001646 is a 24VDC motor. It is not a replacement for 115/208/230VAC single-phase motors, 208/230/460VAC three-phase motors, 50Hz AC motors, or higher-horsepower DC motors. Matching only the physical size or horsepower is not enough. Voltage, horsepower, RPM, shaft, coupler, mounting, wiring, and operator configuration all matter.
If replacing a motor in a hydraulic operator, confirm the motor did not fail because of a locked pump, damaged coupler, hydraulic pressure problem, gate binding, or incorrect adjustment. Installing a new motor without correcting the cause of overload may damage the replacement motor.

Related Parts and Accessories
The correct related parts depend on the operator model, pump pack configuration, shaft/coupler setup, and whether the motor failure was caused by another problem. Inspect the surrounding drive and electrical components before ordering only the motor.
- Motor coupler - verify the correct coupler by operator generation and shaft arrangement.
- MX002054 motor coupler, 5/8 inch shaft, 6T - related coupler used on certain later pump packs; not the motor.
- MX001650 motor coupler, 5/8 inch shaft, 9T, old - related older coupler; not the motor.
- MX001098 mercury contactor - related switching component in some DC systems; not the motor.

- DC power supply, batteries, charger, controller output, and wiring - should be checked during motor diagnosis.
Technician Note
Before replacing MX001646, verify that the motor is actually failed. A DC motor complaint can be caused by low battery voltage, poor DC supply, a bad contactor or relay, loose wiring, controller output problems, a damaged coupler, hydraulic pump load, hydraulic pressure issues, or gate binding. If the motor is overloaded by the pump or gate system, a new motor may fail again.
Check the motor label and compare voltage, horsepower, RPM, shaft arrangement, mounting, and wiring before ordering. Do not replace a 24VDC motor with an AC motor or a different horsepower DC motor unless the HySecurity parts diagram confirms the correct substitution.
Before Ordering, Confirm
- The required part number is MX001646.
- The original motor is 24VDC and rated 3/4 hp.
- The RPM matches the original motor and the parts diagram.
- The operator model and serial number match the parts diagram being used.
- The motor is being used on a DC operator configuration, not an AC 1-phase or 3-phase system.
- The shaft, mounting, coupler, and wiring arrangement match the original installation.
- The motor failure was not caused by a seized pump, hydraulic overload, gate binding, weak batteries, poor wiring, or a bad contactor.
- The package contents include what you need, or that the coupler and mounting hardware are ordered separately if required.
Installation and Service Notes
- Disconnect and secure power before servicing the motor or operator electrical system.
- Do not work on live DC motor wiring or energized operator controls.
- Confirm polarity, wiring, and controller output according to the manufacturer service information.
- Inspect the motor coupler and pump input before installing the replacement motor.
- Do not force an incorrect shaft or coupler combination.
- Check for hydraulic binding or pump drag before returning the operator to service.
- After service, verify smooth operation, correct speed, proper stopping behavior, and all required safety devices.
Professional Advisory
Motor replacement on a HySecurity gate operator should be performed by a qualified gate technician when the repair involves high-current DC wiring, hydraulic pump load, heavy gate movement, travel setup, or safety-critical operation. Do not bypass fuses, overloads, controller protections, limit controls, inherent entrapment sensors, photo eyes, gate edges, or other safety devices to test a motor.
Product Questions & Answers
What is HySecurity MX001646?
HySecurity MX001646 is a 24VDC electric motor rated at 3/4 hp for select HySecurity DC gate operator applications. It should be used only where the parts diagram or original motor label confirms this part number.
Is MX001646 an AC or DC motor?
MX001646 is a DC motor. It is listed as 24VDC and should not be substituted for a 115/208/230VAC single-phase motor or a 208/230/460VAC three-phase motor.
What RPM is the MX001646 motor?
Current product information commonly lists MX001646 as 1800 RPM. Confirm the RPM against the original motor label and HySecurity parts diagram before ordering.
What operators use MX001646?
Current information associates MX001646 with select SwingRiser B and C speed systems and HySecurity StrongArm DC models where the parts diagram lists this motor. Always verify by operator model and serial number.
No. MX001646 is a 24VDC motor. MX001910 and MX001634 are related 3/4 hp AC motors with different voltage and phase requirements, so they are not interchangeable.
Does this motor include the coupler or pump pack?
Package contents should be verified before ordering. The motor coupler, pump pack, wiring, or mounting hardware may be separate unless the current product listing specifically includes them.
What should be checked before replacing this motor?
Before replacing the motor, check the DC power supply, batteries, wiring, contactor or relay, controller output, motor coupler, pump load, hydraulic pressure, and gate movement. These issues can mimic a failed motor or damage a new motor.
