DM165 Oil Cooled Drum Motor Supports Long Running Postal Conveyor Operations
A postal sorting conveyor doesn't get much time to rest. Parcels keep moving. The line keeps running. Dust keeps building up.
For a major postal distribution center in China, the conveyor system needed a drive unit that could handle long working hours without frequent maintenance stops. The site runs around 16 hours every day, with parcel weights ranging from 10 kg to 50 kg. The conveyor speed reaches 1.3 m/s, which puts steady pressure on the drive system.
Winroller supplied the DM165 Oil Cooled Drum Motor for this belt conveyor project. The motor works under S1 continuous duty conditions and drives an 8-meter conveyor line. Its sealed structure, IP67 protection, and long lubrication cycle help the equipment keep running in a dusty sorting environment.
No complicated external transmission parts. No frequent chain adjustments. Just a compact drive unit built for continuous material handling.

The Challenge: Long Hours, Dust, Limited Maintenance Time
The working environment in a postal sorting center isn't easy.
The conveyor line needs to keep pace with parcel processing schedules. A short equipment stop can affect the whole workflow. Maintenance teams usually don't have much time to inspect and repair equipment during daily operation.
The main challenges included:
- Continuous operation for long shifts
- Dust exposure from daily parcel handling
- Stable speed requirements during sorting
- Limited opportunities for maintenance
For this type of application, the drive system needs to focus on reliability rather than just output power.
DM165 Oil Cooled Drum Motor for Postal Conveyor Applications
The DM165 Oil Cooled Drum Motor combines the motor, gearbox, and drum into one integrated unit.
This design saves installation space and removes external transmission components such as chains, couplings, and belt drives. Fewer moving parts mean fewer areas that require regular checking.
The IP67-rated housing helps protect the internal components from dust and moisture. The oil cooling system manages heat generated during long operating periods, keeping the motor and gearbox working at a stable temperature.
The sealed lubrication system is another key point for this project. The DM165 can operate for around 50,000 hours before oil replacement, which fits well with logistics applications where stopping equipment for maintenance isn't always practical.
Performance Benefits in the Sorting Line
The DM165 drum motor helps the postal conveyor system achieve:
- Stable parcel transportation at 1.3 m/s
- Reliable operation with 10–50 kg loads
- Continuous S1-duty performance
- Better protection in dusty environments
- Lower maintenance frequency
- Cleaner conveyor structure with integrated drive design
Project Application
A major postal distribution center in China needed a conveyor drive that could handle real working conditions, not just laboratory parameters.
The DM165 Oil Cooled Drum Motor was selected for its enclosed structure, cooling capability, and long maintenance interval. The solution fits postal sorting lines, express logistics conveyors, and other applications where equipment needs to keep moving day after day.
