Among various special-purpose motors, the universal motor operates on both supplies, alternating current (AC) and direct current (DC). In this paper, the design of special purpose 2 poles and 100-watt universal motor has been carried out by ANSYS Maxwell software. The focus is on using the rotor pole embrace factor as a design variable; the analysis is done with the help of the parametric approach based on several iterations. The different performance parameters have been taken into account for design analyses like efficiency, torque, speed, and flux density of air gap of the respective motor. Here, the flux pattern and characteristics of the motor with their respective curves was extracted. The electromagnetic analysis of the proposed motor has been analyzed with the help of the finite element method (FEM).Consequently, it is observed that the optimal model offers a significant enhancement in efficiency without bringing additional losses to the motor.

“…Such pressure pulsations will result in the vibration and noise of the pump (20)(21)(22)(23). In addition, local temperature rise of liquid foods in pump impeller and volute will occur during operation of food transport pumps, which will affect the safety of liquid foods (24,25). Vibration, noise, and temperature rise of liquid foods are inevitable in the process of transfer.…”

In the field of food processing, the processing of liquid foods has always played an important role. Liquid foods have high requirements for the processing environment and equipment. As the core equipment in liquid foods processing, food transport pumps are widely used in liquid foods production, processing and transportation. Most liquid foods are non-Newtonian and vulnerable to vibration, noise, and temperature rise produced by rotary motions of food transport pumps in operation, which can finally affect foods safety. Therefore, this review summarizes the impact of mechanical vibration, noise, and temperature rise on liquid food products, with the aim of ensuring food safety while designing a cleaner, safer and more reliable food transport pumps in the future.

“…Its stator is laminated to prevent eddy currents from forming in all vast metallic surfaces exposed to alternating magnetic fields. The universal motors are employed in equipment that require a lot of torque, like food processors, low-power tools (up to 1200 W), and vacuum cleaners [9,10]. This type of motor has several advantages, including inexpensive cost, small size, and high speed.…”

The universal motor is a rotating electrical machine that can operate on either direct current or single-phase alternating current, similar to a DC motor. It has been widely used in various small and inexpensive drives for a long time, mostly in home appliances and hand tools. The noise generated by a universal motor is believed to be closely associated with the electromagnetic torque fluctuations of the machine, which are caused by variations in the current supplied to the motor. The power electronics utilized for controlling the motor's speed are responsible for these current changes. Accurate high-frequency motor models are crucial for reliable electromagnetic interference simulations in motor drive power electronic systems. Research efforts have expanded to explore different realistic configurations that can be used to investigate the electromagnetic compatibility behavior of electrical machines. This study describes a method for predicting the differential mode impedance of universal motor. The behavior of each motor winding has been individually studied through impedance measurements, starting with the armature, followed by the series winding, and finally the inductive compensating winding. The prediction results over a wide frequency range up to 1 MHz are in good agreement with the measurements and enabled us to propose a model circuit for each motor winding.
