The BRx90-50 is a 90 mm frame, 50 mm stack PMDC motor designed for continuous operation at 3000 rpm with nominal power of 210 W at 24 V. It offers a nominal continuous torque of 0.67 Nm and a stall torque of 5.61 Nm, with a terminal resistance of 0.294 Ω and maximum efficiency of 81%. The motor features an IP54 enclosure, Class F insulation, and reversible operation. When paired with the GB12 gearbox, the assembly adds approximately 110 mm in length, resulting in a 60:1 reduction ratio. Rotor inertia is 6.57 × 10⁻⁴ kg·cm², and weight is 3.60 kg. The unit supports integration with optional brakes, encoders, and shaft extensions.
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 BRx90-50-GB12 is part of our modular range, with this particular combination utlising a 24V, 3000 RPM DC motor and a composite gear, 60:1 ratio right-ange gearbox. The pairing of this motor and gearbox offers 50 rpm and up to 35.1 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.
