Hägglunds storms into new territory with a permanent magnet torque motor: Hägglunds Thunder

Gearless drive solutions from Hägglunds are renowned for their high torque and utter reliability, but also for their flexibility. With the introduction of Hägglunds Thunder, even the route to those advantages is flexible. Based on permanent magnet (PM) synchronous motor technology, Hägglunds Thunder is an electrifying solution from the most trusted supplier of industrial direct drives.

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. By enabling a fully electric, frequency-controlled drive solution from low to megawatt levels of power, the new Hägglunds Thunder creates an additional path to familiar Hägglunds benefits.

“PM synchronous motors are a well-known technology with untapped potential in heavy-duty industrial applications,” says Tor Jensen, Vice President Hägglunds Global Sales. “Our focus on dependable and versatile direct drive solutions hasn’t changed, nor will it. But with Hägglunds Thunder as a complement to our electrohydraulic portfolio, we can offer a true Hägglunds solution with somewhat different drive characteristics. That provides new answers to specific customer challenges.”

Amplified power with full peace of mind

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 a remarkable 300 rpm – and provides constant high efficiency at nearly any speed within its range.

“Customers who require high, or extremely high, torque at speeds close to zero will be better served by Hägglunds electrohydraulic solutions,” 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 seconds. “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.”
