The BRx90-75 is a permanent magnet DC motor with a 90 mm frame and 75 mm stack length, designed for applications requiring controlled speed and high torque output. It is offered in modular configurations with optional gearboxes, brakes, and encoders. The variant identified by part number 781108 operates at 48 V nominal voltage, with a nominal speed of 3000 rpm and a nominal continuous torque of 0.9 Nm. It delivers a maximum intermittent torque of 1.50 Nm for S2 duty cycles of 15 minutes. The motor has an IP54 rating, Class F insulation, and is reversible. Rotor inertia is 8.65 × 10⁻⁴ kg·cm², and weight is 4.00 kg. When paired with the GB9 15:1 composite gearbox, the output speed is approximately 200 rpm and intermittent torque increases to 19.1 Nm, with an additional 138 mm in length. The motor is enclosed and meets EN60034-1:2010 performance tolerances.
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-GB9 is part of our modular range, with this particular combination utilising a 48V, 3000 RPM DC motor and a composite gear, 15:1 ratio right-angle gearbox. The pairing of this motor and gearbox offers 200 rpm and up to 19.1 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.
