Linear Brush Series

Glentek offers the latest in high performance Linear Brush Servo Drives for the control of both DC brush servo motors and voice coil motors. With extensive utilization of surface mount technology and special heat transfer techniques, Glentek’s Linear Brush Servo Drives offer one of the world’s most powerful products for a given form factor. All models can operate in current (torque) or velocity (RPM) mode and accept a +/-10 VDC analog input as a command reference. All models can close the velocity loop via feedback of a DC tachometer. These drives are best suited for low inertia applications that require high bandwidth, low noise and zero crossover distortion and motors or voice coils which require high current loop bandwidths.

Command/Control Modes
+/-10 VDC for current (torque)
+/-10 VDC for velocity (RPM)
Analog tachometer (required for velocity control)
Dedicated Inputs
Single-ended or differential signal command, tachometer, +/- limits, inhibit/enable, fault, reset
Dedicated Outputs
Fault out
Bandwidth All servo drives have a nominal 10 kHz current loop bandwidth which varies with the motor inductance. Higher bandwidths are available upon request.
Linear output stage Provides high bandwidth, low noise and zero crossover distortion.
Multimode operation All models can operate in current (torque) or velocity (RPM) mode and accept a +/-10 VDC analog input as a command reference.
Heat dissipation (@ 25°C): 250 Watts continuous for the SMA5005 and 300 Watts continuous for the SMA5015.
Current limit Peak motor current is adjustable.
RoHS Compliant RoHS compliance optional.
CE Marked All servo drives are CE marked.
Tachometer Required for velocity feedback.
Dedicated inputs +/- limits, inhibit, fault and reset.
External fault reset An input is provided to reset the drive in the event of a fault.
Fault protection Short from output to output, short from output to ground, drive RMS over current, drive under/over voltage (SMA5015 only), and drive over temperature.
Status indicator 7-segment LED display indicates drive status on the SMA5015 and LED’s indicate status on the SMA5005.
Industry standard mounting Available in a Module, Multi-Axis, and Stand Alone configuration. Optional custom mounting configurations are available to meet virtually any requirement.
Ergonomic Design Easy access to connections, adjustments and test points.
SMT construction Provides ultra compact size, cost competitive package and high reliability.
Manual fault reset A push button reset is available on the SMA5015.
