ess complexity, fewer variants, more efficiency, more power; and simpler, faster commissioning and maintenance. Lenze is driving the future of conveyance with a revolutionary new magnetic motor driven roller (MDR) to support intralogistics customers. The o450 MDR will integrate directly into
existing conveyor systems and deliver an output of 115 watts, making it more than twice as powerful as comparable systems on the market. Due to the unique design, this motor has
significantly lower copper and iron losses overall, which means that less heat is generated within the roller. This results in a positive effect regarding efficiency as cooler copper windings have lower resistance (and therefore lower copper losses). The cooler magnets have a higher magnetic flux linkage and can therefore achieve the same torque with a lower current. Depending on the speed, the MDR would therefore fulfill efficiency classes IE7 -IE9; and the customer saves up to 30% energy compared to conventional systems.
14 DESIGN SOLUTIONS MARCH 2024
The o450 from Lenze can handle up to 66 pounds (30 kg). Even at low speeds, it offers the full nominal torque, which is hugely advantageous for accelerating conveyed goods.
MOTOR DRIVEN ROLLER WITH 24V OR 48V The motor transfers its rotational energy via its rotor directly to the conveyed goods or the conveyor belt. The motor is based on the Vernier principle and combines a 3-phase AC motor with a loss-free magnetic gearbox. The advantage over a conventional drive system is that the motor roller operates at 24 V or 48 V, which means non-electricians can replace, maintain, or install the roller. Variances are also reduced by 85% with this gearless MDR. This minimises design resources while minimising excess inventory in a warehouse. Competitors currently have up to ten different gear ratios in their portfolio, according to Lenze. In addition, the cabling effort is also significantly reduced. While comparable
products require cables for speed and temperature monitoring in addition to the power connection, the latter two are integrated into the roller of the Lenze o450.
