Molon CHM-2425-1M 24V Gearmotor
Features: 1.08 A, 24 V, 25 RPM; 50 in-LB torque; continuous duty; DC permanent magnet gearbox with a die-cast zinc case; reversible operation. This model is best for projects that require steady torque at low speed and can handle continuous operation without overheating. Caution: Check mounting and wiring to ensure proper heat dissipation in enclosed spaces. Best for heavy-door mechanisms or precision slow-motion tasks where constant torque is needed.
BEMONOC 12V DC Geared Motor
Features: 12 V, no-load current ≤1.2 A; rated current ≤3.5 A; 45 RPM no-load, ≥35±10% RPM under load; rated torque 6 N·m; 100% duty cycle; includes mounting hardware. Best for applications needing reliable continuous operation with higher torque at modest speeds. Choose this if you require a compact, ready-to-mount unit that runs continuously in damp or variable-temperature conditions. Limitation: confirm precise dimensions (171 x 62 mm) for your enclosure before purchase.
Copkim 12V DC Worm Gear Motor Kit
Features: 12V, 16 RPM no-load, 1:505 reduction, all-metal gears, reversible wiring, and a complete mounting kit (bracket, screws, couplings). Best for hobbyist and small automation projects needing very slow, high-torque drive with straightforward installation. It includes a self-locking feature when unpowered, which is advantageous for stopping or pausing without drag. Caution: wattage and current draw should match your power supply; ensure the included mounting hardware fits your frame size.
Greartisan DC 12V 550RPM Geared Motor
Features: All-metal gears; pure copper wire core rotor; D-shaped output shaft for robust coupling. Best for projects needing a balance of speed and torque with durable construction. Use this when you require consistent performance in environments subject to heat and abrasion. Limitation: higher speeds at 550 RPM may require additional speed control for precise positioning compared to ultra-low-speed gear motors.
uxcell DC24V 80W 160RPM Geared Motor
Features: 24V, 160 RPM, 4 N·m torque; right-angle gearbox; 10 mm shaft; 30 cm cable; robust mounting with M6 holes. Best for higher-voltage applications requiring steady torque at moderate speeds. Choose this if your system already runs on 24V and you need a compact, reliable motor. Limitation: ensure the heat profile fits your continuous-running duty; this model may heat under sustained heavy load.
Buying Guide
Key considerations to match a continuous-duty DC gear motor to your project
- Duty cycle and cooling: Continuous-duty ratings require adequate heat dissipation. Look for explicit 100% duty specifications and consider enclosure ventilation.
- Voltage and current: Align motor voltage with your power supply and ensure the current draw is within your control circuit capabilities.
- Torque and speed: Higher torque at low speed is typical for heavy doors, conveyors, or robotic joints. If you need precise positioning, consider gear reduction and feedback options.
- Gearbox and materials: All-metal gears and robust shafts improve longevity in demanding environments; note shaft shape (D-shaped) for secure couplings.
- Mounting and compatibility: Check bracket compatibility, mounting hole spacing, and connection types (reversible wiring, self-locking features) to simplify installation.
FAQ
- What is continuous-duty in a DC gear motor?
– It means the motor is designed to run without requiring long rests, typically under specified torque and temperature limits. - Which motor is best for high torque at low speed?
– Models with high reduction ratios (like 1:505) or gearboxes designed for low-speed, high-torque output are ideal. - Do these motors need special drivers?
– Depending on the model, you may need a motor driver or controller compatible with your voltage and current requirements. - Is all-metal gearing better than plastic?
– Generally, yes for durability and heat resistance in continuous-duty use, though weight and cost may be higher. - Can I run any DC motor continuously without cooling?
– No. Continuous operation requires adequate cooling, ventilation, and adherence to the motor’s rated duty cycle and temperature.
