LR-500A Set Main Body, Stand, Rod, Stainless Steel Shaft And 75 mm 4-Blade Propeller Overview
A DC brushless 70 W motor drives the gearless direct-drive system, delivering up to 1.96 N·m (20 kgf·cm) of torque through a ø10 mm shaft. Brushless construction removes spark risk and brush replacement. Direct drive keeps noise low and maintenance minimal while sustaining torque on thick media.
Key Features

- Gearless direct drive: low-noise, low-maintenance ø10 mm shaft delivering up to 1.96 N·m torque.
- Speed feedback control: maintains the set rate from 34–340 rpm despite viscosity change, suiting thick solutions.
- Digital display: 3-digit speed readout with an LED torque/overload indicator for live load monitoring.
- Complete set: main body, stand, rod, stainless-steel stirring shaft (ø10 × 500 mm), 75 mm 4-blade propeller, and clamp.
