Plastic planetary gear motors can provide a wide range of gear reduction ratios in a compact package combining high strength, low noise and great value. These features make this gear motor a good choice in various applications, as detailed below.
Plastic planetary gearheads have one or more stages of gear reduction all in line with the motor shaft. Internal gears are made of plastic. The outer body or casing is also made of plastic. Like metal gear planetary gearheads, each stage has three or four gears in mesh, providing considerably greater strength than simple spur gearheads.
Advantages compared to Metal Planetary Gear Motors
- The plastic planetary gear motor body and gears are lighter, reducing the overall weight of the gear motor.
- Plastic gears generate less noise than metal-on-metal gears.
- Plastic gearheads are generally much more cost-effective to produce.
Disadvantages compared to Metal Planetary Gear Motors
- Plastic gears and housings are lower strength and rigidity resulting in lower load capacity.
- Metal gears can be manufactured to higher precision, resulting in higher efficiency, speed, rigidity and lower backlash than plastic gears.
Advantages compared to Metal Spur Gearheads
- The plastic planetary gear motor body and gears are lighter, reducing the overall weight of the gear motor.
- Less noise is transmitted in plastic-on-plastic gearing.
- Higher reduction ratios per stage are possible resulting in a more compact gear motor.
Application Examples
Plastic planetary gear motors are a great option for many applications when noise, weight, or cost are critical factors, including:
- Food & Beverage Applications – Vane pump gear motors, coffee applications
- Vending Machines
- Health Mobility Lifts
- Automatic Swing Doors and Automatic Slide Doors
- Automatic Electric Locks
- Electric Shades and Blinds
- Industrial Applications
