Electric Final Drive M280

Product catalog summary

General Information
The Electric Final Drive M280-120-14-40.5-B80V operates within an ambient temperature range of -20°C to 25°C, with derating required for higher temperatures. It adheres to insulation class EN 60034-1 F(155°C) and has an enclosure type of DIN EN 60529 IP67.

Drive Engine Specifications
The drive engine is a permanent magnet synchronous type with 12 poles and a reducer ratio of 40.5. It weighs 142 kg and delivers a peak torque of 9510 Nm at the flange. The peak current is 660 Arms, with an S2 rated speed of 40 rpm and an S2 60-minute torque of 4630 Nm at the flange.

Electrical Characteristics
The torque constant at the motor shaft is 0.356 Nm/Arms, and the back EMF constant is 30.4 V/1000 min-1. Electrical resistance at 25°C is 1.5 mΩ, and electrical inductance at 1kHz is 40 μH/34 μH.

Mechanical Brake
The brake type is a currentless brake with a braked engine shaft function principle. Activation voltage is 80VDC, hold voltage is 40VDC, and typical braking torque is 9500 Nm.

Feedback and Sensors
The temperature sensor type is PT 1000, and the angle sensor type is a SIN/COS-Encoder. Power supply is 5V +/-5%, with power consumption at 20mA. Output amplitude is 1.1 +/-0.2Vpp, and output offset is Vdd/2 +/- 5mV.

Dimensions and Load
Bearing capacity is specified as C 2 x 309kN and C0 2 x 450kN.

Connections
Power connections require an AMPHENOL Radlock mating connector, part number RL01201-120BK, with a cable size of 120mm2. Signal connections (SIN/COS) use an Amphenol Ecomate RM connector RT06128SNH, with a backshell RT0L-12CG-S1 for 6-10.5mm cables and socket SS20M1F for 0.34-0.5 mm2 cables.
