Ring Motor

ThinGap (Camarillo, CA) introduced the PM model TGO77 large-bore compact ring motor for precision and highspeed applications. The brushless, frameless motor has an outside diameter of 77 mm (3.03"), 59 mm (2.32") inside diameter, and 18 mm (.709") overall height. Continuous torque is approaching 0.2 Nm at speeds up to 30,000 RPM. Vibration-free, high-speed operation is facilitated by a composite aircore winding that features a sinusoidal winding with less than 1% THD. Since there is no iron in the stator, there is zero cogging, zero iron loss, and zero radial forces between the stator and rotor. Low-TML materials are available for vacuum and space-rated applications such as wafer processing and metrology equipment. Adjustable windings are available that cover common bus voltages and speed requirements.

Servo Motor Cable

Lapp Group USA (Florham Park, NJ) introduced ÖLFLEX® SERVO 7TCE flexible, oil-resistant servo cable with TC-ER approval. Because it is suitable for use directly on industrial machines and in cable trays, the cable eliminates the need for two different kinds of cable, or the use of conduit in run. It features a thermoplastic elastomer (TPE) jacket, as well as cross-linked XLPE insulation that can withstand temperatures to 105 °C. In addition to being UV-resistant, the cable is flame-retardant and can resist harsh cleaning solutions. A low-capacitance design enables long-distance runs with limited losses in current and voltage. Nominal voltages are 600V and 1,000V with a minimum bend radius of 6 × cable diameter.

Energy Chain Roller Links

igus (East Providence, RI) expanded the standard, modular system of the E4.1 e-chain series with roller links that are separated so the roller sits in the middle of the link. The links have small ramps in front of and behind the rollers, reducing noise during movement, and helping to avoid hard impacts when the upper run of the chains is unrolled onto the lower run. The rollers are not additional components; they are integrated into the links. The links enable users to switch from gliding to rolling energy chain systems, and to continue using the same trough systems, interior separation, and mounting brackets as before. Due to the modular nature of the series, different sizes and types are possible. No adapter links are needed, and the roller links can be fitted on the left and right side of the chain. The interior contours are smooth, and the crossbars and lids are slightly rounded, creating less wear on the cables during operation.
