In a Brushless DC (BLDC) motor system, an electronic mechanism is required to commutate the system. Unlike a Brush DC motor system, the permanent magnet is located at the rotor and the windings are ...

In a DC motor, the stator is a permanent magnet and the rotor has the windings, which are excited with a current. The current in the rotor is reversed to create a rotating or moving electric field by ...

Both the brushless DC (BLDC) and permanent magnet synchronous motor (PMSM) require electronic commutation in order to create a rotating electromagnetic field, which is needed to turn the rotor. Both ...

Bipolar Hall-effect sensors are used in BLDC motors to detect the position of the rotating magnet. In this example, an eight-pole motor with a three-phase winding uses three bipolar latching ...

Toshiba Electronics Europe has updated and extended its design framework for Brushless DC (BLDC) and Permanent Magnet Synchronous Motor (PMSM) drives. Toshiba has added new features that automatically ...

A family of modular brushless permanent-magnet motors consists of 75‑mm (2.95-in.) squared motors in three stack lengths. Peak motor torque varies from 250 to 630 Ncm (354 to 892 oz-in.) May 4, 2011 A ...

New and increasingly stringent efficiency standards have made motor efficiency a priority among motor manufacturers and designers of motor-driven systems. While the Energy Independence and Security ...

In the previous article, we had a look at the history of motors and their application in early EVs, both on land and water. From the late 19th century onwards, motor technology improved, especially AC ...

Cordless power tools are becoming the primary choice in both the professional and consumer markets for low-to-medium applications (Fig. 1). Workshop tools include screwdrivers, saws, drills, rotary ...
