Machine elements Compact

Machine elements Compact and powerful: universal connector-and-cable system Universally usable solutions are always in demand in the industry. LQ Mechatronik Systeme developed a connector-and-cable system that is worth using in any application where 3-phase and asynchronous motors are deployed in machines and plants. The plug-in connector adopts the geometry of the motor connection box The X-TEC 15 connector combined with the W-TEC 15 power cable is the most efficient connector-and-cable system of its size in the market. Whether the motors are being used in different units, conveyor systems, in pumps or in fans, it is worth using LQ’s technology for any application where 3-phase and asynchronous motors are in use. The system can be used, regardless of the make and manufacturer: it offers an excellent performance yet it is compact in size. It offers an end-to-end solution, from the control to the motor. Using the X-TEC 15 circular plug-in connector, motors can be retrofitted quickly to produce a plug-in solution. Each motor terminal board box contains an M20 connection. The plug-in connector is easy to fit using the M20 x 1.5 thread. There is no need for additional adapters and special mechanical solutions. The plug-in connec- tor adopts the geometry of the motor connection box, no further mechanical work is required. The advantages: wherever this plug-in solution is used in motors, the performance remains the same yet a lot of space is saved. Compact solution, simple handling, low price Depending on where motors are used, space can be a problem. The compact size of LQ’s solution means that use under cramped conditions is not a problem. An end-to-end solution is also possible with the appropriate W-TEC 15 cable. Both parts together form the most efficient connectorand-cable system of its size, with 6 x 2.5 mm² continuous operation at 16 A on the power contacts and 10 A on the auxiliary contacts. With the X-TEC 15 and W-TEC 15 LQ Mechatronik-Systeme GmbH has created an excellent connector-andcable solution for varied applications such as motors in various units, conveyor systems, pumps and fans. With LQ’s solution complicated superstructures which take up space are no longer required.

Product News Compact ball-screw stage with linear encoder by Aerotech Aerotech has introduced MPS75SLE, a compact and linear high-performance positioning stage. Together with a linear encoder with low-thermal expansion, the precise ball-screw ensures high accuracy, repeatability, and a 25 nm positioning resolution. Anti-creep crossed-roller bearings enable smooth motion and high load capacity in a compact design. The ideal fields of application include optics positioning, z-axis positioning of sensors in surface metrology, and general high-precision alignment. Multi-axis stage configurations can be achieved by using the adapter plates and mounting, which are compatible with the MPS product range, and other linear and rotary stages of the MPS product range. The linear encoder is available for integration with all standard controllers with amplified sine (1 Vpp) or TTL digital outputs (50 nm). A DC servo motor with a high-resolution rotary encoder or a stepper motor are available for the axes. An optional mounting plate provides direct mounting to both English and metric optical breadboards. www.aerotech.com EtherCAT Box: Compact I/O modules in a die-cast zinc housing With its ER series, Beckhoff has extended the fields of application of the EtherCAT Box modules. The I/O modules in a die-cast zinc housing are suitable for particularly harsh environments, for example in the heavy-duty, automotive or robotics sectors. The modules, with IP 67 rating, have digital inputs with different filters, digital outputs with 0.5 A output current and combination modules with freely selectable digital inputs or outputs. Moreover, analog input modules for current/voltage measurement, temperature measurement modules, serial interfaces, encoder inputs, and motion modules are available. The models in different channel variants are 30 or 60 mm wide, 126 mm high and 26.5 mm deep. The signal connection is achieved via M8 or M12 plugs. The modules have an EtherCAT interface, power supply and M8 connectors or sockets for forwarding. www.beckhoff.com Linear axes by Rollon for light to medium loads The Smart linear units manufactured by Rollon GmbH consist of a self-supporting aluminum profile, on which the recirculating ball bearings are mounted with high load ratings. The drive is achieved via steel-reinforced polyurethane toothed belts with an AT tooth profile. In the E-Smart series, the rotor is supported by a recirculating ball bearing, as in the case of the S-Smart series, which is designed for vertical installation. The R-Smart series is designed for higher load ratings. For this reason, in this case, the carriage runs on two parallel recirculating ball bearings. With the new R-Smart 220 SP size, the manufacturer has rounded up its axis series. As for the existing sizes (120 and 160), it can be equipped with two different lengths of rotor variants. B&R introduces premium IP65-rated helical gearboxes B&R Industrie-Elektronik has added two helical models to its premium gearbox series: the 8GP70 series with a shaft output and the 8GF70 series with a drive flange. The features of these new products include, among other things, excellent synchronization characteristics and a low noise level at higher speeds, as well as low circumferential backlash, which is also available as a low-backlash option (
