How to choose a motor for gear reducers
The standard product for gear reducers uses a low-voltage, three-phase induction motor with a fully enclosed external fan squirrel rotor. Gear reducers are divided into three types: two-stage, three-stage, and connected. It is mainly composed of parts such as casing, gears, shafts, bearings, and bearing covers, and is widely used in large-scale mining, steel, chemical, port, environmental protection and other fields.
general considerations
1. Power supply: single-phase, three-phase, voltage cycle, transformer capacity, etc.
2. Load machinery: required horsepower, load torque characteristics.
3. Special usage conditions:
a. Quickly reverse or stop.
b. Frequent startup and shutdown.
c. A particularly large starting torque is required.
d. When connected to reciprocating machinery.
How to choose a motor for a gear reducer? Please confirm from the following aspects:
1. Power: DC/AC
2. Environment: Explosion proof/Corrosion proof/Low noise/Moisture/Temperature/Altitude
3. External cover: cooled/open/fully closed
4. Dimensions: Standard Metric sys. IEC.BS.IIS Metric/English sys. NEMA/Indication
5. Voltage: Dual voltage: 200/400220/380220/440230/460208/415
Single voltage: 200/230350/380400/415440/460V
6. Frequency: 50/60HZ
7. Number of phases: single-phase/three-phase
8. Polar number: Single series: 2, 4, 6, 8
Variable levels: 2/4, 4/8, 6/12, 4/6, 6/8, 6/12
9. Insulation: Moisture resistant insulation/Cold resistant insulation/Oil resistant insulation
10. Braking: DC/AC
