M3 (48V)

Product catalog summary

General Information
The Electric Final Drive M3 (48V) 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.

Drive Engine Specifications
The drive engine is a permanent magnet synchronous type with 12 poles and a reducer ratio of 34. It weighs 62kg and can achieve a peak torque of 2420 Nm at the flange with a peak current of 210 Arms. The continuous torque at 30 1/min is 1240 Nm with a continuous current of 106 Arms. The maximum speed at 48VDC is 47 1/min, with a torque constant at the motor shaft of 0.35 Nm/Arms and a back EMF constant of 29.8 V/1000 min-1. Electrical resistance at 25°C is 6 mΩ, and electrical inductance at 1kHz is 130 μH/108 μH.

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

Feedback and Sensors
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. The output amplitude is 1.1 +/-0.2Vpp, and the output offset is Vdd/2 +/- 5mV, with an internal serial impedance of 720Ω.

Dimensions and Load
The bearing capacity is specified as C 2x57500N and C0 2x78000N.

Connections
Power connections require an Amphenol Surlock Plus mating connector with part number SLPPA16BSO, which is not included. The cable size is 16mm2 with a diameter of 8.1 +/-0.2mm. Signal connections for SIN/COS require an Amphenol Ecomate RM mating connector with part number RT06128SNH, which is also not included.
