| Parameter | 24V Brushless (BLDC) | 24V Brushed DC |
|---|---|---|
| Efficiency | 85–92% | 70–80% |
| Service life | 20,000+ hours (bearing-limited) | 2,000–5,000 hours (brush-limited) |
| Maintenance | Bearing lubrication every 5,000–10,000 hrs | Brush replacement every 3–6 months (continuous duty) |
| Brush dust | None | Yes — problematic for food, medical, cleanroom |
| Noise / EMI | Low | Higher (arcing, commutator ripple) |
| Speed control | Electronic controller (Hall + MCU) | Simple PWM or potentiometer |
| Upfront cost | Higher (motor + controller) | Lower (motor + PWM driver) |
| Total cost / 5 years | Lower (no brush replacement, less energy) | Higher (brush cost + downtime + energy) |
| Best for | Conveyor, packaging, medical, AGV, 24/7 automation | Gate opener, occasional actuator, cost-driven consumer |
24V DC Gear Motor — Brushed & Brushless For Conveyor, Packaging, Automation & Medical
24V is the standard industrial control voltage — and the most popular voltage class for DC gear motors in factory automation, packaging, and material handling. At 24V, the motor integrates directly with PLC outputs, industrial sensors, and standard power supplies without voltage conversion. Shenghe manufactures both brushless (BLDC) and brushed DC gear motors at 24V across 57mm, 80mm, and 86mm frame sizes, paired with planetary, worm, spur/helical, or right-angle gearboxes. Need help choosing? See our DC gear motor selection guide.
Brushed vs Brushless at 24V
Which 24V DC Gear Motor Variant Fits Your Application?
Both variants share the same frame sizes and gearbox options at 24V. The difference is inside the motor housing — and it drives lifespan, efficiency, noise, and total cost.
Decision rule: if the motor runs >4 hours/day or operates in food/medical/cleanroom environment, specify BLDC. For deep technical comparison, read our DC gear motor selection guide.
Where 24V DC Gear Motors Are Used
- Conveyor belt drives — 100W–400W with spur/helical gearbox for smooth, efficient continuous operation on packaging lines
- Packaging machinery — labeling, filling, sealing machines; 50W–300W with planetary or right-angle gearbox for precise positioning
- AGV auxiliary drives — steering, lifting, turntable rotation; 50W–200W planetary gearbox with low backlash
- Automatic doors & gates — sliding doors, swing gates, barriers; 60W–200W worm gearbox for self-locking under load
- Medical equipment — hospital beds, patient lifts, surgical table positioners; BLDC required for IEC 60601 EMC compliance
- Robotic actuators — collaborative robot joints, pick-and-place arms; 50W–300W planetary gearbox for low backlash
- Solar trackers — single-axis and dual-axis tracking; brushed DC with worm gearbox for self-locking (intermittent duty, cost-sensitive)
- Food processing — mixer drives, filling machines, conveyor lines; BLDC with NSF H1 food-grade lubrication option
