The BRx70-40 is a 48 V permanent magnet DC motor with a 70 mm frame and 40 mm stack length, designed for applications requiring controlled speed and high torque. It operates at a nominal speed of 3000 rpm with a continuous torque of 0.25 Nm and a stall torque of 2.4 Nm, delivering a nominal power of 79 W. The motor has a terminal resistance of 1.86 Ω and a torque constant of 0.13 Nm/A, with maximum efficiency of 78%. It is enclosed, rated IP54, and features Class F insulation. The part includes a GB12 60:1 right-angle gearbox, adding approximately 110 mm to the length. Rotor inertia is 1.83 × 10⁻⁴ kg·cm², and it supports reversible operation. Weights 1.85 kg.
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 BRx70-40-GB12 is part of our modular range, with this particular combination utlising a 48V, 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 12.6 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.
