Leroy-Somer has introduced the 3000 series helical geared motor range, comprising three modular families. The axial-output Compabloc is available in nine sizes up 10,000Nm, while 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, 3000 series units are claimed to deliver up to 30% more torque than similar-sized, competing products.
Dust and damp ingress protection has been improved, while a 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. Mounting options include MI with integral motor, MU universal using a standard B5 IEC motor and AP input shaft with optional AP/AD anti-runback.
An 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.
