In the first installment of this series, "Calculating a practical hotspot safety margin", we discussed how two-parameter thermal models assume that the entire motor, including windings, exhibits one ...

The use of a copper winding as a temperature sensor is not new. The traditional technique is to disconnect the ac power and the load and to quickly make the measurement using an ohmmeter. But the ...

Build in a thermal safety margin to handle servomotors that heat up more than theoretical models predict when the torque cranks up. • The relationship between intermittent and continuous torque is ...

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 ...

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 ...

Small and medium AC induction motors account for more than 75% of motor electrical energy demand; however, they typically receive less maintenance than their larger counterparts. This leaves them ...

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 ...
