General Information
The Electric Final Drive M280-120-14-81.5-B80V operates optimally in ambient temperatures ranging from -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.

Performance Characteristics
The drive engine is a permanent magnet synchronous type with 12 poles and a reducer ratio of 81.5. It weighs 167kg and can achieve a peak torque of 19100 Nm at the flange. The peak current is 660 Arms, with an S2 rated speed of 20 rpm. The S2 60-minute torque is 8780 Nm, and the current is 336 Arms. The torque constant at the motor shaft is 0.35 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 drive features a currentless brake with a braked engine shaft principle. Activation voltage is 80VDC, and hold voltage is 40VDC, with a typical braking torque of 19100 Nm.

Feedback
The system includes a PT 1000 temperature sensor and a SIN/COS-Encoder angle sensor. The power supply is 5V +/-5%, with a power consumption of 20mA. Output amplitude is 1.1 +/-0.2Vpp, and output offset is Vdd/2 +/- 5mV, with an internal serial impedance of 720Ω.

Dimensions and Load
The 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 sockets (8x) SS20M1F for 0.34-0.5 mm2 cables.
