• The thermal models that servomotor manufacturers provide may not hold for brief periods of superhigh torque. • More accurate thermal models for periods of high performance use equations with more ...

The use of a copper winding as a temperature sensor for transformer windings is not new. But the circuit presented here goes further. It can make the measurement in-circuit and in real time. The use ...

For safe, long-term use of a compressor, the motor winding temperature must be kept below certain limits, in all conditions in which the appliance may operate. For example, compressors from AC ...

High-performance motion control demands compact and economical servomotors. Fortunately, because most servo applications only intermittently demand maximum continuous-torque motor output, a smaller ...

SICK has launched the sHub® sensor hub, a smart add-on to its HIPERFACE® DSL single-cable motor feedback system, which turns servo motors into a source of data for real-time condition monitoring and ...

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 ...

Although technically a lot simpler, mechanical speaking, than their internal combustion engine (ICE) counterparts, electric cars are also a lot more complicated. That's because they rely on a wide ...

Electrical equipment often has at least one motor used to rotate or displace an object from its initial position. There are a variety of motor types available in the market, including induction motors ...
