The neuroscience community has long desired microscopes that support both 3D, high-speed photoactivation and full-field, deep ...

Porsche 911 Carrera GTS T-Hybrid ushers in a new generation of exotically hybridized, voltage-enhanced engines. Dan Neil says ...

Like the BLDC motor, it operates in synchrony with the rotating magnetic field generated by the stator ... owing to the extensive availability of appropriate variable-speed drives to deliver the ...

For instance, if the grinder encounters a stone, the motor will shut off to prevent further damage to the burrs.” While variable burr rotation speed is becoming a popular performance feature in the ...

Consequently, the motor operates at a “slip”— a few percent shy of synchronous speed. Figure 4. Shaft rotation (left ... a hit when operating at varying speeds and loads—driving a variable-speed pump ...

These three main components can then provide variable-speed control of one or more three-phase induction ... is only allowed when the motor is not rotating. In the automatic operation bypass mode, the ...

Most EVs rely on a direct-drive (single-ratio) unit to step down the rotating speed between ... all-important variable RMF. But it's worth pointing out that these electric motors are also ...

A vehicle transmission transmits the rotating power ... the rotation of the motor to the rotation of the wheels. But it is more accurately called a single-speed gear reduction unit since the ...
