High-Performance Hall Sensor Amplifier Optimizes Performance of Brushless Motors

July 23, 2008
Portescap, a Danaher Motion Company, introduces the RoHS-compliant EBL-H-50-03 four-quadrant amplifier. With fully programmable features, this hall sensor amplifier is specifically engineered to optimize the performance of Portescap brushless motors in applications such as Bi-PAP respirators where efficiency, high acceleration or safety is of primary significance. All inputs and outputs are clearly identified to facilitate easy startup in less than 10 minutes. With a compact footprint of 92 x 72 x 16 mm and weighing just 45 grams (1.5 oz), the EBL amplifier is ideal for portable equipment applications where size and weight are significant design considerations. A broad supply-voltage range of 5.5 – 50 V enables accurate control of Portescap’s 16-30mm brushless motors at speeds up to 90,000 rpm. The EBL amplifier also provides continuous current output of 3 amps, and maximum current output of 12 amps. Thermal, short and over current protection are included as standard, while an optional start up current limitation feature helps protect surrounding equipment, such as a battery pack. An external temperature sensor (i.e., motor case temperature) can be connected to the amplifier to protect the application from overheating. The EBL amplifier can be factory-customized to satisfy specific application requirements by programming the level of current protection and PI regulation parameters.
