Portescap Introduces Driver for Brushless Motors

Portescap has introduced its ROHS compliant EBL-H-50-03 brushless driver, engineered for Brushless motors. With a speed range of 90,000 RPM, and a maximum current output of 12 amps, the amplifier provides a continuous current output of 3 amps and a supply voltage of 5.5-50 Volts. Weighing in at under 2 oz, the new amplifier is able to provide a broad supply voltage range, which makes the driver capable of controlling the smaller 13mm BLDC motors to the larger 30mm motors.



The EBL amplifier can be customized by the factory for specific application by programming the level of current protection and PI regulation parameters. With a compact footprint of 92 x 72 x 16 mm and weigh just 45 grams (1.5 oz), the EBL amplifier is 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. They also provide continuous current out- put 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 your application from overheating.
