Product Introduction

Products Description

Electrical Steel Motorized Pulley Roller Drum Motor

product-579-284

The design of the electric drum allows the motor and reduction gear to be installed within the drum housing, forming a closed drive unit that greatly prevents external influences.

Even under harsh operating conditions, sufficient size of individual parts can ensure a long service life. The most advanced production methods ensure low noise and efficient operation. The clamping pins on both sides are flat and use two-piece clamping bearings to achieve simple and time-saving assembly.

Applicable conditions:

A. The drum shall be installed horizontally, with an inclination angle not greater than 5 degrees;

B. Ambient air temperature - 20 to 40 degrees Celsius;

C. Rollers with an altitude of not more than one kilometer and specially designed to meet the requirements of more than 5000 meters;

D. The temperature of the conveyed material shall not exceed 60 degrees Celsius;

DRUM MOTOR BENEFITS

Reduced energy consumption

Compared to many corresponding motor and gearbox systems commonly used in industry, Srollmart drum motors are able to use less energy for the same performance, helping to reduce power consumption, benefi ting the environment and reducing energy costs.

Designed for the toughest conditions

The Srollmart drum motor is designed to operate perfectly even in the most aggressive environmental conditions such as, in the presence of water, dust, grit, chemicals, grease, oil and even during high pressure wash-down procedures.

Increased efficiency

Srollmart drum motors have a higher effi ciency compared to traditional motor transmission systems, which are normally able to transfer approximately 75% of the power used to the belt. Srollmart drum motor is able to transfer up to 97% mechanical effi ciency.

Guaranteed for food

Thanks to its fl at smooth surfaces, stainless steel fi nish and totally enclosed, hermetically sealed design, Srollmart drum motors are easy to clean reducing contamination risk in food processing environments.

Ease of installation

Srollmart drum motors are much faster and easier to install when compared to traditional multiple component motor transmission systems, typically requiring less than a quarter of the time for installation. With fewer parts to consider, conveyor design and assembly is easier and quicker, procurement is also simplifi ed reducing overall costs.

Safety

Component parts are totally enclosed within a Srollmart drum motor. With the external shafts held captive in a conveyor frame, the only moving part is the body of the pulley running under the conveyor belt. Conveyors can be designed in such a way preventing any of the drive pulley to be visible, resulting in an extremely safe method to drive conveyor belts.

Space-saving design

With motor, bearings and gearbox enclosed inside the casing, drum motors are very compact, requiring less space, increasing the aesthetic and functional value of the finished conveyor.

Maintenance-free

The fully sealed design ensures that internal parts are not exposed to external environmental conditions or tampering. A completely self contained unit, requiring no maintenance throughout its service lifetime.

Products Application

APPLICATIONS FOR SROLLMART DRUM MOTORS

Standard conveyor belts

To drive standard belts using the friction between the drum motor shell and the underside of the conveyor belt. The belt, which passes over the drum motor works as a heat sink, taking the heat produced by the electric motor and allowing it to dissipate away

Thermoplastic positively driven belts

Thermoplastic belt applications require drum motors to be fi tted with profi led lagging to suit, in order to provide positive drive. Please contact Srollmart to select optimum drive solution.

new energy vehicle

Plastic modular belts For applications that involve the use of plastic modular belts, it is necessary to cover the drum motor with a profi led lagging or to fi t laser cut profi led sprockets to the shell of the pulley, to provide positive drive to the belt. Please contact Srollmart to select optimum drive solution.

Non-Belt applications

For applications that do not require the use of belts, such as for moving product in direct contact with the pulley, or for brush cleaning applications. To prevent overheating we would recommend the adoption of frequency converters. Please contact Srollmart to select specifi cation.
