“…Magnetic stirrers typically use an induction motor called a shaded pole motor. This motor is an alternating current (ac), single phase, asynchronous, squirrel cage rotor, featuring low cost and high durability; however, they have low efficiency and low torque. This motor class is used in various domestic equipment, mostly fans used in microwave ovens, fryers, grills, dryers, freezers, etc .…”

Considering the large number of magnetic stirring hot plates that are damaged or unused in chemical laboratories, this Technology Report presents guidelines for students to be able to diagnose problems, and repair and maintain magnetic stirring hot plates using common and low-cost parts, or even repurposed materials. In addition, this paper presents a control board for stirring or heating with a circuit that uses the triode for alternating current BTA08, as well as various suggestions for refurbishing, maintaining, and replacing parts. Guidelines are provided for diagnosing equipment and conducting a cost analysis to determine the economic viability of proposed maintenance and repair approaches.

“…When studies in the literature are examined, Pessina and Morra found that the component of the magnetic field rotating in the opposite direction of the double short circuit ring motor is less and therefore the vibrations in the torque characteristic are reduced [5]. Makowski obtained the electromagnetic torque value and performance characteristic by considering the saturation and skewing of the rotor bars [6].…”

Abstract-Due to their robustness, operation from a single phase supply and low cost the shaded pole induction motors (SPIM) are widely used in very low power industrial applications and household appliances. Despite all these advantages the nature of their design alleviates some complicated problems in their analysis and limits the efforts devoted to their performance improvement. In this investigation using Finite Elements Method (FEM) an electromagnetic model of a variable air-gap reluctance SPM motor is built and the effect of geometrical variations of the stator and rotor structures on the performance improvement has been studied. To this end the rotor has been designed as single cage and double cage with different geometries and different types of materials. In addition, the stator is arranged with bridge or without bridge and also with the different inter-pole gap in the bridgeless motor. Finally effect of all these geometrical variations on the motor performance have been studied comparatively.

Single-phase motors are widely used in household applications. Shaded-pole and splitphase capacitor-start single-phase induction motors are very popular for their ruggedness and their comparatively low cost. Recently, line-start single-phase motors are gaining market shares. However, their superior efficiency and torque density are counterbalanced by the higher cost of the rotor construction due to the magnets. This chapter compares the main structures of single-phase line-start motors, presenting their lumped parameter models and the finite element analysis. The equivalent circuits of the single-phase induction motor and of the line-start permanent magnet are derived. Different rotor structures for single-phase line-start permanent magnet (PM) motors are compared. The finite element method (FEM) is used to compare the characteristics of the motors. Motors with the same stator have been tested. No-load and load tests have been performed and compared to the FEM simulations and to the analytical model. Finally, the performances of line-start PM motors are compared to the shaded-pole induction motors in terms of torque density and efficiency.
