Electric Final Drive M350

Product catalog summary

General Information
The Electric Final Drive M350-120-10-i101.8-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, with IP69K available as an option.

Performance Characteristics
The drive engine is a permanent magnet synchronous type with 12 poles and a reducer ratio of 101.8. It weighs 263 kg and can achieve a peak torque of 38,000 Nm at the flange with a peak current of 1131 Arms. The S2 rated speed is 20 rpm, with a 60-minute torque of 20,500 Nm and a current of 642 Arms. The torque constant at the motor shaft is 0.33 Nm/Arms, and the back EMF constant is 28.3 Vrms/1000 min-1. Electrical resistance at 25°C is 0.5 mΩ, and electrical inductance at 1kHz is 17µH/15µH.

Mechanical Brake
The brake is a currentless type with a nominal voltage of 80VDC, typical braking torque of 38,000 Nm, activation voltage of 80V, and hold voltage of 40V.

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

Dimensions and Load
The bearing capacity is C 2x315kN and C0 2x570kN. Power connections use an Amphenol SURLOCK PLUS/RADLOCK mating connector, while signal connections (SIN/COS) use an Amphenol Ecomate RM connector RT06128SNH with a backshell RT0L-12CG-S1 for 6-10.5mm cables. The socket (8x) is SS20M1F for 0.34-0.5 mm2 cables, which are not included.
