Description
EP300 Modular Planetary Drives
The EP300 family is the core modular industrial planetary-drive platform for applications that need compact coaxial power transmission and a broad torque ladder. The catalogue separates reference torque, required torque, service factor, thermal capacity, efficiency, speed, and life factor so the gearbox is selected from the duty rather than from motor power alone.
Torque Classes
Use the reference-torque ladder to identify the starting gearbox size. Final selection must also check service factor, required life, input speed, thermal duty, radial or axial loads, and mounting configuration.
| Basic Size | Catalogue Reference Torque |
|---|---|
| EP300 | 1,000 N·m |
| EP301 | 2,000 N·m |
| EP303 | 3,000 N·m |
| EP305 | 5,000 N·m |
| EP306 | 8,500 N·m |
| EP307 | 12,500 N·m |
| EP309 | 18,500 N·m |
| EP310 | 25,000 N·m |
| EP311 | 35,000 N·m |
| EP313 | 50,000 N·m |
| EP315 | 80,000 N·m |
| EP316 | 105,000 N·m |
Selection Logic
For a first pass, calculate application output torque and multiply it by the service factor. The resulting calculated torque must remain within the rated output torque for the selected life factor. Continuous-duty applications also require a thermal-power check, especially when ambient temperature or input speed differs from the catalogue reference condition.
Do not select only from peak motor power. Reversals, starts per hour, shock load, duty cycle, and output speed can change the required frame size.
Drive Interfaces
EP300 drives can be configured around electric or hydraulic prime movers, different output arrangements, and application-specific mounting. The RFQ should identify the input source, shaft or flange connection, rotation, mounting position, and any external radial or axial load.
Engineering Inputs
| Input | What To Provide |
|---|---|
| Required output torque | Continuous, peak, and starting torque if known |
| Speed | Input speed and target output speed |
| Duty | Hours/day, starts/hour, reversals, shock level |
| Interface | Input adaptor, output shaft/flange, mounting position |
| Environment | Ambient temperature, dust, moisture, washdown |
| Life target | Expected working hours or maintenance interval |
Application Fit
This modular family is a strong starting point for conveyors, mixers, process equipment, winches, heavy material handling, and custom machinery where torque density and packaging space matter. For mobile travel, wheel, or slew functions, the dedicated EP400, EP600, and EP700 families provide application-specific support arrangements.
FAQ
Is the reference torque the same as my required torque?
No. Reference torque is a sizing class. Required torque and service factor must be checked against the rated torque for the intended life.
Can EP300 be used with hydraulic motors?
Yes, the catalogue selection logic covers electric, hydraulic, and other drive units; the exact adaptor and brake arrangement must be confirmed.
What information is needed for replacement selection?
Send the existing nameplate, ratio, input and output interfaces, mounting drawing, duty, and photos. Do not rely on outside dimensions alone.
Are dimensions identical across all EP300 sizes?
No. Each basic size and construction version has its own dimensional data and interface options.
Data Note: EP300 torque classes and selection logic are sourced from the connected HZPT / Ever-Power planetary gearbox catalogue. Final configuration is subject to engineering confirmation.
