The PM70-146 is a 48V permanent magnet DC motor with a 70 mm frame, 60 mm stack length, and 146 mm overall length. It delivers 157 W nominal power at 3000 rpm with a continuous torque of 0.5 Nm and a nominal current of 4.2 A. Stall torque is 3.6 Nm at a stall current of 28.7 A. The motor achieves a maximum efficiency of 82%, has a terminal resistance of 1.51 Ω, and a torque constant of 0.130 Nm/A. It is enclosed, IP54 rated, and features Class F insulation. Rotor inertia is 2.5 × 10⁻⁴ kg·cm², and it supports reversible operation. The motor weighs 2.25 kg and has two poles.
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 PM70-146 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 48 volts and rotates at 3000 rpm. With a stack length of 60 mm and an overall motor length of 146 mm, the motor has an output power of 157 watts and produces 0.5 Nm of continuous torque.
