Glentek's SMA6520 series linear servo amplifiers provide the optimum solution for applications which require high current loop bandwidth, low radiated electrical noise and zero crossover distortion. These amplifiers incorporate our latest generation ISO-BIAS current sense technology which provide one of the lowest drift linear amplifiers on the market today. These amplifiers are constructed using surface mount technology and incorporate the latest in heat transfer technology which make them one of the most powerful amplifiers for a given form factor.

Typical applications which are ideal for the SMA6520 series amplifiers include low inductance/resistance brushless amd brush motors (linear or rotary), high resolution linear brushless motor stages and voive coil motors.

The Trapezoidal Linear brushless servo amplifier accepts a +/-10V analog input as a command reference and commutates the motor trapezoidally using Hall sensors or commutation tracks from an encoder. It operates in current (torque) mode and has an option to operate in velocity (RPM) mode with the input of a tachometer. This amplifier is best suited for low inertia applications that require high bandwidth, low noise, zero crossover distortion and where slight torque ripple is acceptable. Following is a list of the Trapezoidal Linear servo amplifiers that Glentek offers: SMA6520-50HS-12.

The 2-Phase Current Mode Linear brushless servo amplifier accepts two +/-10V analog inputs as current command references for two of the motor phases and derives the third command reference. The 3-Phase Current Mode brushless servo amplifier accepts three +/-10V analog inputs as current command references for three of the motor phases. This amplifier is best suited for low inertia applications that require high bandwidth, low noise, zero crossover distortion and are used with controllers that provide the commutation. Following is a list of the 2-Phase/3-Phase or Voice coil (DC Brush) Current Mode servo amplifiers that Glentek offers: SMA6520-50HS-11.
