Enabling a fully electric Hägglunds direct drive
A PM synchronous torque motor is a type of multi-pole electric motor, capable of delivering high torque that fits well alongside that of existing Hägglunds motors. Based on this technology, the new Hägglunds Thunder offers proven benefits of Hägglunds drive technology and enables a fully electric, frequency-controlled drive solution from low to megawatt levels of power.
“PM synchronous motors are a well-known technology with previously untapped potential in heavy-duty industrial applications,” says Tor Jensen, Vice President Hägglunds Global Sales. “Our focus on dependable and versatile direct drive solutions remains unchanged. But with Hägglunds Thunder as a complement to our electrohydraulic portfolio, we can offer a true Hägglunds solution with somewhat different drive characteristics. That opens up new solutions for specific customer challenges.”
Amplified power with proven reliability
While the specifications for Hägglunds Thunder fit neatly within the Hägglunds portfolio, they create a distinct performance envelope. The Hägglunds Thunder motor range has a nominal torque of up to 200 kNm, and it provides fully variable speed from standstill. Nominal operating speed begins at 30 rpm, which is slightly higher than solutions based on the existing Hägglunds portfolio. Yet the Hägglunds Thunder range opens up to 300 rpm – and provides near-constant efficiency at any speed above nominal.
“Customers who require high, or extremely high, torque at speeds close to zero, Hägglunds electrohydraulic solutions are an ideal choice,” says Uno Sundelin, Project Manager for Hägglunds Thunder. “But where the requirements for torque and speed are a good fit, we can use Hägglunds Thunder to supply excellent direct drive solutions for up to 4300 kW of power. That’s a bold new peak, even for Hägglunds.”
Besides such efficient power, Hägglunds Thunder offers solid protection, sustaining a 200 % overload for up to 60 s. “Reliability in unpredictable applications is what customers have come to expect from Hägglunds,” says Sundelin. “They’ll find that Hägglunds Thunder sacrifices nothing in that regard.”
