The Parvalux BRx90-75 is a permanent magnet DC motor with a 90 mm frame and 75 mm stack length, designed for applications requiring precise speed and torque control. This model, in the 781108 variant, operates at 48 V nominal voltage with a nominal speed of 3000 rpm and delivers a continuous torque of 0.9 Nm at a nominal current of 7.3 A. It has a stall torque of 7.71 Nm and a maximum intermittent torque of 1.50 Nm for 15-minute cycles. With a terminal resistance of 0.426 Ω and a rotor inertia of 8.65 × 10⁻⁴ kg·cm², it features an IP54 enclosure, Class F insulation, and reversible operation. When paired with the GB12 gearbox, the assembly provides a 15:1 reduction ratio, reducing output speed to approximately 200 rpm and increasing intermittent torque to 16.9 Nm, while adding 110 mm to the overall length.
With their high starting torque, Parvalux PMDC right angle gear motor solutions are ideally suited to applications where speed must remain under control. Standard products are available in the following performance ranges:
• Speed 0.2 - 1390 RPM
• Torque 0.1 - 150 Nm
• Power 23 - 750 Watts
The Parvalux BRx90-75-GB12 is part of our modular range, with this particular combination utlising a 48V, 3000 RPM DC motor and a composite gear, 15:1 ratio right-ange gearbox. The pairing of this motor and gearbox offers 200 rpm and up to 16.9 Nm of torque in intermittent operation (S2 – 15 minutes). As part of the modular range, you can also add accessories such as brakes, encoders, and shaft extension kits to fine tune your combination to perfectly meet the requirements of your application.
