Getting on the Right Motion Bus

As modern machines have become more advanced, the complexity involved in motion control has escalated. Today, servos have replaced cams and gears on machines and multiple axis of synchronized motion control have become commonplace. Distributed motion control requires busses able to handle rigid jitter and timing demands including:

Integrated Motor Control Meets Aviation Needs

The trend in aircraft design is toward more efficient brushless DC motors. A integrated motor drive module for brushless DC motors from International Rectifier (El Segundo, CA) reduces the effort of programming the motor control and simplifies certification. Because the device is configured for sensorless field oriented control, the elimination of Hall sensors improves reliability while reducing component count. It enables the aircraft to achieve greater fuel economy and lower maintenance costs.

Motor Control Chip

The Magellan programmable motion processor chip from Performance Motion Devices (Lincoln, MA) controls any combination of DC brush, brushless DC, microstepping, or pulse and direction motors. Each controlled axis supports profile generation, servo loop closure, PLC-style signal manipulation, and motor signal generation. Advanced features include programmable PID filters with velocity and acceleration feed-forward, 32-bit position error, and 50 microsecond loop time. Selectable profile modes include S-curve, trapezoidal, velocity contouring, and electronic gearing.

Piezoelectric Stage

The P-737 PiFOC Piezo-Z stage from Physik Instrumente L.P. (Auburn, MA) uses deconvolution and 3D imaging techniques. It provides up to 250 micrometers of travel, millisecond response, and nanometer precision motion under closed-loop control. The stage achieves 10 to 50 times faster response than conventional stepper motor drives. It is available with a choice of analog and digital piezoelectric controllers and accepts digital and analog input signals. The stage is compatible with many image acquisition packages and includes LabView drivers.

Rotary Seal

American High Performance Seals (Pittsburgh, PA) has announced its Rotaflon rotary seal which minimizes shaft damage and reduces power consumption. The seal accommodates changing operating conditions, low breakout force, and provides superior chemical resistance. It accommodates surface speeds to 5900 ft/min and temperatures from -58 F to +500°F and is suited for poor lubrication conditions.
