When the motor current reaches a pre-defined current limit (such as 190 percent or 250 percent), the speed drops, but it recovers more quickly than with the liquid rheostat
, according to the company.
The use of storage cells to supply current to the comparator has not been contemplated, and the regulating rheostats
have such ranges of resistance as to permit the use of dry cells having an initial emf of not over 1.
People think AC drives and liquid rheostats
are maintenance free, but they require just as much service as a DC System.
Speed control is provided by two liquid rheostats
(adjustable resistors with separable electrodes in a water/sodium-carbonate electrolyte).
My 'bots lived in an alternate universe controlled with hand-wound rheostats
and 3-phase power, nothing remotely connected to reality.
the world's leading passive and connector specialist in the electronics industry, today announced that the company has entered into a global distribution agreement with Ohmite, a leading manufacturer of power resistors and rheostats
Typical applications for these devices include remote-keyless-entry keyfobs, remote controls, security systems, cellular telephones, battery chargers, wristwatches, clocks, thermometers, rheostats
, thermostats, toys, PC peripherals and sensors.
various values and ratings Escorp/EPL/Sigma, Soldering Gun with changeable bits 25 watts, Resistance Bridge( Including P.
In addition to electrical and power resistors, Ohmite also produces rheostats
and tap switches and services the makers of motor controls, test and measurement equipment, medical equipment and power conversion equipment.
The PIC12C671 and PIC12C672 target applications in which the environment (pressure, temperature, motion, acceleration, gas concentration and sound) is being monitored and/or measured in a variety of products, such as smart sensors, intruder detectors, security systems, tire pressure gauges, water meters, CO detectors, exhaust systems, smoke detectors, portable voice recorders, intelligent thermostats, rheostats
, safety devices for consumers products, automatic temperature shutoff of electric appliances, automotive "creature comforts," battery chargers and rechargeable battery packs.
Contract award: egpa 759 - supply of steel rheostats
and complete packs for acceleration and braking power.
Typical applications for the PIC12C508 and PIC12C509 include personal care appliances, remote transmitters, sensors and detectors, portable voice recorders, security systems, transponders, RF tags, rheostats
and rechargeable battery modules.
