Signal amplifier / pulse width modulation

Aerotech's stand-alone drive for three-phase AC brushless and single-phase DC brush motors are The BA series amplifiers. Using a self-commutating, low ripple, modified six-step algorithm, this durable amplifier can run in velocity mode or torque mode. A standard ±10 VDC as a velocity or torque (current) command from any motion controller is accepted by all BA amplifiers . External commutating controllers to bypass the BAs commutation and perform sinusoidal commutation use the dual phase mode in order to provide the smoothest velocity control. The BA amplifier requires only AC line power which makes it completely self-contained and the amplifier is fully protected. Loop noise is minimized by the DC-isolated power stage. The amplifier accepts a quadrature encoder or tachometer input for velocity feedback. The encoder signal is converted to a voltage representing speed. Three models are available for the BA, up to 100 A peak to match your application power requirements. Stock delivers standard models.
