The BLM700 is a multipurpose closed loop brushless dc motor
control designed for OEM and MRO applications where energy efficiency, space,
installation cost and tight motor speed regulation are a must. Typical applications include commercial
cooking and industrial process conveyor ovens; material handling systems; printing
and labeling equipment; chemical metering pumps; batching and blending
applications. The BLM700 is brushless
motor control, digital closed loop, ratio control, process alarm and
programmable rate meter all in one integrated package. The BLM700 utilizes
concepts from the field tested Dart
Micro-Drive Series, with the added benefit of energy
efficiency. Brushless DC motor drive
technology is the most efficient drive technology. The BLM700 overcomes the typical higher
initial investment hurdle found with other brushless solutions by incorporating
many other typical motor loop functions into one package. By eliminating these other components
(tachometer feedback, alarm relays, ratio control and tachometer) and the
installation cost associated with them, the BLM700 actually SAVES money over
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
The Window Watcher stops the burglar before he does damage or enters the house. House alarm service companies set off alarms and call the service only after the burglar has damaged and entered the house.
