General Information
The Electric Final Drive M3i50 (96V) is designed to operate 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 IP68.

Performance Characteristics
The drive engine is a permanent magnet synchronous type with 12 poles and a reducer ratio of 50.2. It weighs 62kg and can achieve a peak torque of 3190 Nm at the flange with a peak current of 320 Arms. Continuous torque at 30 1/min is 1716 Nm with a continuous current of 161 Arms. The maximum speed at 96VDC is 100 1/min, with a torque constant at the motor shaft of 0.22 Nm/Arms and a back EMF constant of 19.1 V/1000 min-1. Electrical resistance at 25°C is 2.5 mΩ, and electrical inductance at 1kHz is 71 μH/58 μH.

Mechanical Brake
The drive features a currentless brake with a braked engine shaft principle. Typical braking torque is 2550 Nm, with an activation current of 1.05A and a hold current of 0.25A. The typical resistance is 14Ω.

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
Bearing capacity is specified as C 2x57500N and C0 2x78000N.

Connections
Power connections require an AMPHENOL SURLOCK PLUS mating connector (part number SLPPA25BSO), which is not included. The recommended cable size is 25mm2. Signal connections for SIN/COS require an Amphenol Ecomate RM mating connector (part number RT06128SNH), which is also not included.
