Dynabloc - High Performance Geared Servo Motors Temperature rise class F Ambiant temperature 40°C Power supply 380-480 V AC (230 V on request) Nominal speed 2000 to 6000 rpm The exact backlash for each gearbox type and ratio i is specified in § Technical characteristics. The torsional stiffness is the characteristic which indicates the torque in N.m which must be applied to the servo gearbox to deform it by an angle of one arcmin. The stiffness is indicated in N.m/arcmin. In the event of very severe applications combined with a high inertia of the load, it is advisable to choose a servo...

Dynabloc - High Performance Geared Servo Motors Selection criteria Selection flow chart Select the gearbox type (Pje, Pjr, Mjd, Ot, Cb, Mb) depending on the output (in-line or right angle) and the angular backlash required. Calculate the torque Mres applied on the output shaft Calculate the total torque Mres + Macc on the output shaft Select the gearbox in the selection tables in function of the requested torques and speed Verify that : kS1 x Mn red ≥ Mres Verify that : kacc x Macc red ≥ (Mres + Macc) x F1 x F2 Verify the ratio of the moments of inertia Jch/Jmot (load/motor) Verify the...

• Low backlash • High torsional stiffness • Lightweight and compact • Unimotor fm or hd Pje Dynabloc servo gearboxes are designed to reduce the speed and increase the torque of servo motors and to optimize the ratio of inertia between the driven load and the motor. Pje Dynabloc gearboxes are the perfect economical solution for applications requiring low backlash and high torsional stiffness. Lightweight and compact, the gearboxes can be easily integrated into machines. Maintenance-free, they are supplied lubricated and are mulitpositional. Pje Dynabloc gearboxes are available with Unimotor...
