Gear motors

Incorporating 9-slot stator and 12-pole rotor construction design, the TAM58-3E "Industrial Series" family of brushless dc gear motors is designed to offer constant speed in a package made for small space applications. The motor and on-board electronics are controlled by a single 24V dc power supply, while a 5V square wave output tachometer sends 45 pulses/rev at 100 rpm without distortion.

Servodrive system

The BURNY(R) ServoPak(R) AC8 reportedly provides 8A continuous output current in a brushless ac servodrive system. Custom configurable to fit any output power need, it features a digital sinusoidal servo design, with Windows-based BURNY Motion View Software for real-time viewing and off-line software downloads. Applications for the 2-axis or 3-axis packages include shape-cutting uses, and cantilever or gantry machines.

Safety couplings

Made with a Belleville spring, these safety couplings disengage in a problem situation in 2 to 4 ms, according to the company. With one revolution, the coupling re-engages at the exact angular position. Precision roller guides with a wider contact surface offer zero-backlash motion control and high stiffness. Couplings are available with a torque range of 9 to 14,160 in-lb.
