Drives propel multi-axis motion
Drive systems based on parallel kinematics with electromagnetic and electro-ceramic drives can improve dynamics, resolution and accuracy in applications needing high precision and multiple degrees of freedom. Stefan Vorndran, Vice President Marketing Scott Jordan, Director of NanoAutomation Technologies, Physik Instrumente L.P. (PI) Motion simulation is often a crucial piece of the design process for evaluating […]
High-performance magnetic encoder modules offer new options
Encoder Products Company is announcing additional options for their low-profile 30-mm diameter magnetic encoder modules. The Model 30M and Model 30MT provide accurate incremental feedback, even in harsh operating conditions, by means of advanced sensing and signal processing technology. Now with upgraded options to choose any resolution from 1 to 1,024 and 1 to 16 […]
How do gearmotors impact reflected mass inertia from the load?
In any drive system (that is, a motor driving a load), there is going to be inertia. Specifically, the motor will have inertia as will the load. For a direct drive system (a direct motor-to-load connection) the individual inertias can just be added together in a straightforward way. However, for any other type of setup involving […]
Zero backlash featured in Miki Pulley CSZ electromagnetic clutches
Miki Pulley’s CSZ electromagnetic clutches have a zero backlash design and provide an efficient connection between a motor and a load with low inertia, minimal drag and zero backlash. CSZ clutches function using the magnetic force generated by the energized coil providing engagement of input and output members of the clutch. They feature an integrated […]
New panel-mount servo drives from AMC for brushed, brushless dc motors
The AB25A100 PWM servo drive from Advanced Motion Controls is designed to drive brushless and brushed dc motors at a high switching frequency. The drive is fully protected against over-voltage, under-voltage, over-current, over-heating and short-circuits across motor, ground and power leads. Furthermore, the drive can interface with digital controllers or be used stand-alone, and requires […]
Controller for voice-coil and single-phase motors features 192 kHz servo rate
Aerotech’s XL4s linear amplifier is designed for closed-loop servo control of voice coil and single-phase motors, eliminating the non-linearities common with PWM amplifiers. The XL4s provides deterministic behavior, auto-identification, and easy software setup and features a multi-core, double-precision, floating-point DSP that controls the digital PID. All parameters are software-settable including control-loop gains and system safety […]
