HySecurity MX001920 Motor Brush Kit Details
The HySecurity MX001920 is a replacement motor brush kit for select HySecurity 24VDC Smart DC gate operator motors. This kit includes four replacement brushes used inside compatible DC motor assemblies to help maintain proper electrical contact between the brush assembly and the motor commutator.
This is a service replacement kit, not a complete motor. It is commonly ordered when the motor brushes are worn, chipped, contaminated, unevenly worn, or no longer making reliable contact. Worn motor brushes can contribute to weak motor performance, intermittent operation, reduced torque, arcing, motor noise, motor stall symptoms, or failure of the operator to move the gate properly.
The MX001920 brush kit is commonly listed for HySecurity Smart DC 24VDC operator motors and is often associated with SwingSmart DC and SlideSmart DC service parts. Because HySecurity operator generations and motor assemblies can vary, this kit should be matched by part number, operator model, and the correct parts diagram before ordering.
Compatible With
The HySecurity MX001920 brush kit is commonly associated with the following operator and service applications:
- HySecurity Smart DC 24VDC motor assemblies
- Nice HySecurity Smart DC operator motor service applications
- HySecurity SwingSmart DC operators where MX001920 is shown in the parts diagram
- HySecurity SlideSmart DC operators where MX001920 is shown in the parts diagram

- Motor maintenance where the original brush kit is identified as MX001920
Not Intended For
- Replacing a complete motor assembly. This kit includes motor brushes only unless otherwise stated.
- Replacing a gearbox, belt, pulley, control board, encoder, harness, battery, charger, or complete operator assembly.
- HySecurity hydraulic operators, AC motor operators, barrier arms, or non-Smart DC models unless the parts diagram specifically calls for MX001920.
- Motors with damaged commutators, burned windings, seized bearings, water intrusion, or internal motor damage that cannot be corrected by brush replacement.
- Universal motor brush replacement where brush size, lead style, spring fit, and motor compatibility have not been verified.
- Correcting gate movement problems caused by a dragging gate, bad gearbox, weak batteries, failed charger, bad control board, damaged wiring, or failed brake components.
Important Ordering Warnings
- Confirm the exact HySecurity part number before ordering. This listing is for MX001920.
- Public parts listings identify MX001920 as a replacement brush kit for 24VDC Smart DC operator motors.
- The kit includes four motor brushes.
- Do not order by appearance alone. Motor brush dimensions, lead style, spring pressure, and motor fit must match the original motor assembly.
- If the motor has heavy arcing, a burned smell, damaged commutator, water damage, seized bearings, or repeated brush failure, a complete motor repair or replacement may be required.
- If the gate is binding or the operator is overloaded, new brushes may wear quickly or fail again.
- Disconnect all power sources before servicing internal motor or operator components.

Common Related Items
Depending on the reason the motor brushes are being replaced, the following related components may also need to be inspected:
- 24VDC Smart DC motor assembly
- Motor commutator and brush holder area
- Motor wiring and brush leads
- Motor bearings and shaft condition
- Gearbox or drive assembly connected to the motor
- Drive belt, pulley, or sprocket components where applicable
- Operator batteries and charging system
- Smart DC controller board if motor output or motor commands are inconsistent
- Gate hardware, hinges, rollers, chain, or track depending on the operator type
Technician Note
Motor brushes wear as part of normal DC motor operation, but fast brush wear usually points to another issue. Before replacing the brushes, inspect the commutator for scoring, burning, uneven wear, heavy carbon buildup, or contamination. Also check the motor bearings, motor wiring, brush holder area, batteries, charger, and the mechanical load on the gate.
If the operator has been running with a weak battery, dragging gate, bad gearbox, tight hinges, damaged rollers, or a heavy mechanical load, the new brushes may not correct the root problem. Brush replacement should be treated as part of a complete motor and operator inspection, not just a quick parts swap.
Before Ordering, Confirm
- The required replacement part number is HySecurity MX001920.
- The operator uses a compatible HySecurity 24VDC Smart DC motor.
- The parts diagram calls for MX001920 as the brush kit.
- The existing motor uses a four-brush replacement set.
- The brush holders, springs, leads, and motor wiring are not damaged.
- The commutator is serviceable and not badly burned, grooved, or damaged.
- The motor bearings and shaft are not seized or excessively worn.
- The gate moves freely and is not overloading the motor.
- The batteries and charging system are in good condition.
- You are ordering the brush kit only, not a complete motor assembly.
Professional Advisory
Motor brush replacement requires access to internal operator and motor components. Disconnect all power sources before service, including AC power, DC battery power, and any connected solar charging circuit. DC operator motors can move unexpectedly if power remains connected or if the gate is under load.
If the motor has repeated brush failures, heavy arcing, a burned commutator, water intrusion, bearing noise, weak torque, intermittent operation, or wiring damage, the repair should be handled by a qualified gate technician. Replacing the brushes without correcting the root cause can lead to repeat failure or motor damage.
Product Questions & Answers
What is included with the HySecurity MX001920 brush kit?
The HySecurity MX001920 brush kit includes four replacement motor brushes for select 24VDC Smart DC motor applications.
What operators use the MX001920 brush kit?
MX001920 is commonly associated with HySecurity 24VDC Smart DC motors, including select SwingSmart DC and SlideSmart DC applications. Always verify the operator parts diagram before ordering.
Is this a complete motor?
No. This is a replacement brush kit only. The motor, gearbox, controller, batteries, charger, wiring, and drive components are separate parts.
Can worn brushes cause weak motor performance?
Yes. Worn or contaminated brushes can reduce motor contact and may cause weak operation, intermittent movement, arcing, noise, or motor stall symptoms.
Should I replace the motor instead of the brushes?
If the motor commutator is badly burned, grooved, wet, contaminated, or the bearings are noisy or seized, a complete motor repair or replacement may be needed instead of only replacing the brushes.
Will this fit all HySecurity DC operators?
No. This brush kit should only be used where the operator model and parts diagram call for MX001920. Do not order by appearance alone.
What should I check before installing new motor brushes?
Check the commutator, brush holders, springs, leads, motor wiring, bearings, batteries, charger, and mechanical gate load before installing the new brush kit.
