The PM70-125 is a 48V permanent magnet DC motor with a 70 mm frame, enclosed IP54 construction, and Class F insulation. It delivers 79 W nominal power, 3000 rpm at nominal speed, and 0.25 Nm continuous torque (S1). The stack length is 40 mm, rotor inertia is 1.83 × 10⁻⁴ kgcm², and weight is 1.85 kg. Maximum intermittent torque is 0.42 Nm for S2-15 min operation. Terminal resistance is 1.86 Ω, stall current is 18.7 A, and stall torque is 2.4 Nm. Efficiency reaches 78%, with a speed constant of 66.6 rpm/V and torque constant of 0.13 Nm/A. Radial load capacity is 200 N at 15 mm from the flange.
Cost-effective with a high starting torque, Parvalux PMDC motors can be combined with one of our gearboxes to reduce speed and increase torque for the ultimate solution.
• Speed: 1000 - 5000 RPM
• Power: Up to 600 Watts
• Continuous torque: 0.038 - 1.2 Nm
Motor Design The 2-pole bi-directional PM70-125 is enclosed and sealed to IP54, protecting it from dust particles and water spray. Built-to-class F insulation means it can operate in extreme temperatures. This motor operates at 48V and rotates at 3000 rpm. With a stack length of 40 mm and an overall motor length of 125 mm, the motor runs at 79 watts and produces 0.25 Nm of continuous torque.
