Leroy-Somer has introduced the 3000 range, comprising three modular families of helical-geared motors. The axial-output Compabloc series is available in nine sizes up 10,000Nm. The Manubloc series, available in six sizes up to 5,000Nm, features the same helical gears, but with parallel output. The Orthobloc series delivers its output via helical bevel gears and is available in seven sizes up to 10,000Nm. Whatever the version, the advanced design of the 3000 Range delivers up to 30% more torque than similar-sized competitors. Dust and damp ingress protection has been improved, while a re-designed removable panel gives easy access for inspection and preventative maintenance. It’s even possible to change the input gear without having to remove the gearbox.
A variety of mounting options are available for maximum versatility, including MI mounting with integral motor, MU universal mounting using a standard B5 IEC motor and AP input shaft with optional AP/AD anti-runback. The sturdy monobloc-cast housing is designed to provide maximum resistance to radial forces and deformation – making it ideal for even the most demanding applications. Substantial mounting flanges and feet simplify installation and further improve torque resistance.
A key feature of the 3000 range is its modularity: A novel integral mounting allows the same MI motor to be used on all three gearbox series, reducing the number of spare parts required. The same Leroy-Somer integrated motors can also now be used across the entire Compabloc, Orthobloc and Manubloc 3000 range, making them the ideal choice for a wide variety of applications including ATEX dust, ATEX gas, variable speed, food and beverage and many others.
A wide variety of mounting configurations combine with various drive options for maximum versatility. Universal, integral and input shaft mounting variants are available, together with variants featuring an integrated VARMECA variable-speed drive.
