Product Description:

The 20BA150FFWB4B Servo Amplifier belonging to the BL Super Servo Amplifiers series is a reliable brushless motor control module. Sanyo Denki manufactured this amplifier for industrial automation applications and it ensures smooth and accurate motor performance.

The 20BA150FFWB4B servo amplifiers come with breakers rated at 7.5 amperes that serve as overcurrent protection for it and prevents excessive current from damaging internal components. It is designed to drive motors with a maximum power output of up to 0.75 kW which indicates a relatively low to mid range power servo system, suitable for precision applications rather than heavy industrial loads. It comes with labels for different electric terminals such as N, P and E for Neutral (N), Phase (P) and Earth (E) connections. To control the servo motor it uses digital or analog Pulse Width Modulation (PWM) signals which allows for precise speed, position and torque adjustments. The operating temperature range within which the amplifier functions reliably is 0°C to 55°C. It is designed to handle approximately 7.5A of operating current and its alignment with the NFB breakers ensures that normal operation stays within the protected current range. It runs on a single phase power supply which makes it suitable for smaller industrial or commercial applications. It can work in high humidity environments provided that there is no condensation.

The 20BA150FFWB4B servo amplifiers can be stored in temperature range -40°C to 70° without damage which suggests ruggedness and durability and makes it suitable for industrial storage conditions. It is specifically made for brushless servo motors, which are more efficient that require less maintenance and have a longer lifespan compared to brushed motors. This module instantaneous peak current output to the servo motor can reach up to 150A.
