NICE / APOLLO SPMTG02900, ELECTRIC MOTOR
The NICE Apollo SPMTG02900 is a service replacement electric motor assembly for the M7BAR barrier arm operator family. In a barrier operator, the motor assembly provides the driving force that raises and lowers the arm through the internal gearbox and drive mechanism. When the original motor group begins to fail, the barrier may move slowly, stall under load, make abnormal mechanical noise, trip faults, or fail to complete travel even when the controller and safety inputs are working correctly.
This part should be treated as an M7BAR-specific motor assembly, not a general M-Bar motor for every model. The M3BAR, M5BAR, M7BAR, and LBAR families share a similar product line, but their motor groups and mechanical arrangements may vary by arm length, R10 generation, gearbox design, and parts revision. Before ordering, compare the original motor assembly, harness routing, worm gear arrangement, and operator model tag. Also check spring balance and arm hardware, because a poorly balanced barrier can overload a good motor.
Compatible With
- Nice Apollo M7BAR barrier arm operators using SPMTG02900 as the replacement motor group
- M7BAR R10 applications when the parts diagram identifies SPMTG02900
- Select Nice M-Bar barrier installations where the original motor assembly part number matches SPMTG02900
- Not a confirmed replacement for M3BAR, M5BAR, LBAR, Titan, 7200/7300 slide, or Apollo swing operator motors unless the exact parts diagram matches

Technician Note
A weak or stalled barrier motor is often a symptom, not always the root cause. Check spring tension, arm balance, gearbox drag, brake release, and incoming power before condemning the motor.
Before Ordering
- Confirm the original motor label or parts diagram shows SPMTG02900
- Verify the operator is an M7BAR or matching M7BAR R10 service application
- Compare harness connectors and worm gear arrangement with the old assembly
- Inspect spring balance and barrier arm hardware for binding
- Do not substitute a smaller M3BAR/M5BAR motor kit for this assembly
Professional Advisory
Motor replacement inside a barrier cabinet involves moving mechanical parts and electrical power. Disconnect power and use a qualified gate technician if wiring, brake circuits, or high-voltage supply checks are needed.
Product Questions & Answers
Is SPMTG02900 for the M7BAR barrier operator?
Yes. Available references identify SPMTG02900 as an electric motor group or motor assembly for Nice Apollo M7BAR barrier operators.
Does this fit M3BAR or M5BAR operators?
Do not assume that it does. M3BAR and M5BAR use different service references in many parts diagrams. Use SPMTG02900 only where the original diagram or motor label confirms it.
What symptoms can point to a bad barrier motor?
Slow movement, motor noise, stalling, overheating, failure to raise the arm, or repeated travel faults can point to motor trouble after balance, power, brake, and controller issues are ruled out.
Is the worm gear included?
This part is commonly described as a motor assembly with worm gear and harnesses, but kit contents should still be verified from the current supplier listing.
Can an unbalanced barrier damage the new motor?
Yes. A barrier arm that is out of balance or binding can overload the motor and shorten the life of the replacement assembly.
