Frequently Asked Questions
What are the advantages of a 370 planetary gear motor over spur gear motors?
Planetary gearboxes distribute the mechanical load across multiple gears (planet gears), resulting in significantly higher output torque, superior load capacity, lower running noise, and a longer overall service life in a compact footprint.
What is the standard voltage and speed range for this motor?
The typical rated operating voltage ranges from 6 V to 12 V DC. No-load motor speeds range from 4,000 to 12,000 rpm, which can be modified via the gearbox to achieve final output speeds between 10 rpm and 1,000 rpm.
Can these planetary gear motors be used in precision applications?
Yes. Because of their stable torque distribution and low backlash nature, they are highly suitable for precision motion control systems, such as automated valves, robotic joints, smart locks, and precision medical instruments.
What materials are used to construct the planetary gearbox?
The gearboxes are constructed using durable high-precision metals, typically steel or brass gears. This ensures structural strength and prevents wear under continuous operation or heavy stall conditions.
What gear ratios are commonly available?
Standard reduction gear ratios start from 1:10 up to 1:300+. This wide range allows users to select the ideal speed-to-torque conversion ratio required for their specific motion profile.
