Selection table for ECG-A4M gearmotor
The speed and tangential force values refer to a motor roller with a diameter of 50 mm.
Gear- Gear ratio i | Number of gear unit stages | Rotational speed min -1 | Ma Nm | Mapk Nm | MHpk Nm |
|---|---|---|---|---|---|
45 | 3-stage | 12.8 – 155.6 | 2.95 | 8.12 | 7.94 |
33 | 17.6 – 212.5 | 2.16 | 5.96 | 5.82 | |
18 | 2-stage | 31.6 – 382.5 | 1.25 | 3.30 | 3.10 |
15 | 38.5 – 466.7 | 1.00 | 2.70 | 2.54 | |
11 | 52.6 – 637.5 | 0.75 | 2.00 | 1.86 |
i | Gear unit ratio |
Ma | Maximum permitted output torque for continuous duty |
Mapk | Maximum permitted output torque for short-time duty, maximum of 1 min at 30% cyclic duration factor |
MHpk | Maximum permitted holding torque for short-time duty, maximum of 10 min at 50% cyclic duration factor |
The torques listed in the table refer to a maximum ambient temperature of 20 °C, higher ambient temperatures lead to reduced power output. The drive is protected from overheating by a thermistor installed in the motor. The actual current profile depends on the application and the mechanical construction of the conveyor.
