Integrated Conveyor Drive
Permanent Magnet Synchronous Electric Drum Drives
A permanent magnet synchronous electric drum integrates the direct-drive motor with the conveyor drive pulley. It can reduce external mechanical transmission components and installation space for suitable projects.
The supplied file lists torque rows from 4.8 to 21.4 kN·m, pulley diameters from 500 to 1000 mm, and belt widths from 650 to 1200 mm. Voltage fields are incomplete, so electrical data must be confirmed on the selected model sheet.

Where an Integrated Drive Can Help
Removing an external reducer and coupling can simplify the layout. The project still needs a check of torque, overload, cooling, control, braking, backstop, mounting, bearings, access, and environment.
- Compact drive-station layout
- Fewer external transmission components
- Variable-speed control by matched drive
- Multi-drive balance subject to engineering

Electrical and Mechanical Confirmation
Release the selected drum with a model-specific data sheet. Confirm voltage, current, torque, speed range, insulation, enclosure, cooling, controller, mounting, lagging, sensors, and allowable environment.

Frequently Asked Questions
Short answers to the commercial and technical questions buyers usually ask before they compare suppliers.
What information is needed for a conveyor quotation?
Send the material, bulk density, lump size, capacity, horizontal and lift distances, route profile, loading points, discharge arrangement, duty hours, power supply, quantity, destination, and required documents. A route drawing is especially useful.
Can the conveyor be supplied as a complete system?
Yes. The quotation can cover the structure, belt, idlers, pulleys, drive, take-up, cleaners, chutes, guards, controls, spare parts, documentation, inspection, packing, and export coordination. The final scope is listed line by line.
Are the values on this website final design values?
Published tables are preliminary references from the supplied product files. Final capacity, speed, power, belt rating, pulley size, braking, take-up, structure, and protection devices are confirmed against the selected model and project conditions.
Can Zhongmei quote replacement parts for an existing conveyor?
Yes. Send the current model, drawings, nameplate photos, dimensions, shaft and bearing details, belt specification, operating problem, and quantity. A sample or measured drawing may be needed for non-standard parts.
Need a Quote for PM Electric Drum?
