A DC motor is an electrical motor that uses direct current (DC) to produce mechanical force. The most common types rely on magnetic forces produced by currents in the coils. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor. DC motors were the first form of motors to be widely used, as they could be powered from existing direct-current lighting power distribution systems. A DC motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small DC motors are used in tools, toys, and app…

A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source and utilizing an electric brush for contact. Existing DC generators use a commutator to achieve DC output instead of AC output, without commutation of voltage or current. However, because the rotor rotates, the existing voltage-time curve resembles y = a |sin(t)|, causing the voltage to not always be at its maximum output voltage. If the rotor's motion were changed from rotation to repeatedly oscillating and cutting the magnetic field lines perpendicular to them, the voltage output efficiency could be increased, making it closer to a straight line, i.e., y = a. The hi…

Investigation of magnetic orientation effects on interior rotor BLDC motor performance for EVs: a response surface methodology approach.. Interior rotor brushless DC motors (BLDCMs) are lightweight, compact, and efficient, offering high torque over a wide speed range, which makes them well suited for electric vehicle (EV) applications. However, cogging torque (CGT) remains a significant challenge, as it leads to noise, vibration, torque ripple, and jerky operation in EVs. In this work, an interior rotor BLDCM is designed with a focus on magnet orientation tuning combined with rotor skew angle adjustment, which is distinctly different from conventional magnet geometry modification or slot sk…

Efficient speed and voltage regulation of BLDC motor drive for EV applications using a multi-device interleaved DC-DC bidirectional converter with TIFDNFD-SFOA controller.. Electric vehicles (EVs) are emerging as a key solution for sustainable transportation, where efficient motor drives and power electronic interfaces play a crucial role in ensuring reliable performance. In modern EV systems, simultaneous regulation of motor speed and DC-link voltage is essential for stable inverter operation and improved drive efficiency; however, many existing studies primarily focus on speed control while giving limited attention to coordinated voltage regulation. To address this challenge, this researc…

A comprehensive review on charger technologies, types, and charging stations models for electric vehicles.. Electric vehicles (EVs) are popular now due to zero carbon emissions. Hence, with the advancement of EVs, charging station (CS) design also plays a vital role. CS is generally called a charge or power supply point and delivers power to the EVs. Usually, CSs are either of the direct current (DC) type, as the EVs need a DC supply or in some cases of the alternating current (AC) type, as the traditional power grid delivers AC power. Usually, on-board chargers (on-BCs) and off-board chargers (off-BCs) are used to charge the EV batteries. Due to heavy loads, size, and budget constraints, m…

An electric motor is a machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate Lorentz force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor but operates inversely, converting mechanical energy into electrical energy. Electric motors can be powered by direct current (DC) sources, such as from batteries or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators. Electric motors may also be classified by considerations such…
