Motion control specialist Dunkermotoren has expanded its range of gearboxes with the PLG 63hp, PLG 75hp, and PLG 95hp. These have been developed to provide nominal torque of up to 160N•m and acceleration torque of up to 320N•m.
Among the challenges they focused on is surge loads which can occur in emergency stops, misuse or through vandalism in public facing applications. Even under the pressures of occasional load peaks of up to 480N•m these new gearboxes remain undamaged and continue to operate normally.
Saving space is often a key objective for machine builders and these new gearbox options ensure a very compact drive & gearbox solution. These planetary gearboxes are designed so that they do not require any coupling or flange to be mounted to the motor which results in the drive length being reduced to an absolute minimum. When tooth motor shafts are utilized, one stage gearboxes can be achieved with a reduction ratio of 14, 5:1.
