PMDC motor gives higher torque even at lower speeds and maintains speed stability despite viscosity or volume changes. Accurate stepless speed control allows smooth variation upto 1200 rpm. Stirring is accomplished by a small Teflon coated magnetic paddle to be placed in the container. Supply : 220-240 Volts 50 Hz Single Phase.
