BODINE ELECTRIC motor Germany BODINE ELECTRIC model BODINE ELECTRIC price

BODINE ELECTRIC motors are a type of motor that changes the motor speed by altering the number of magnetic pole pairs, voltage, current, frequency, and other methods to achieve higher performance. Due to their excellent performance, adjustable speed motors are widely used in industrial sectors such as steel, power stations, cables, chemicals, petroleum, cement, textiles, printing and dyeing, papermaking, and machinery for stepless speed control of loads with constant torque or decreasing torque. They are particularly suitable for driving pump and fan loads with significant flow variations, achieving good energy-saving results

BODINE ELECTRIC motor advantages

The motor's magnetic field is generated by permanent magnets, thereby avoiding excitation losses (i.e., copper losses) caused by generating the magnetic field through excitation current. The rotor operates without current, significantly reducing motor temperature rise; under the same load conditions, the temperature rise is more than 20K lower. Permanent magnet synchronous motors have a high power factor, which is independent of the number of motor poles. At full load, the power factor approaches 1, resulting in lower motor current compared to asynchronous motors, consequently reducing stator copper losses and increasing efficiency. In contrast, the power factor of asynchronous motors decreases as the number of poles increases. Furthermore, due to the high power factor of permanent magnet synchronous motors, the capacity of the associated power supply (transformer) can theoretically be reduced, allowing for a reduction in the specifications of associated switchgear and cables. Permanent magnet synchronous motors also offer advantages such as high starting torque, short starting time, and high overload capacity. The installed capacity of the equipment drive motor can be reduced based on the actual shaft power, saving energy and reducing fixed asset investment. Permanent magnet synchronous motors are easy to control, with constant speed that does not vary with load or voltage fluctuations but depends only on frequency, ensuring smooth and reliable operation. Due to strict speed synchronization and good dynamic response, they are suitable for variable frequency control. The installation dimensions of permanent magnet synchronous motors comply with IEC standards, allowing direct replacement of three-phase asynchronous motors. The protection rating can reach IP54 and IP55, and some manufacturers also produce explosion-proof permanent magnet synchronous motors.

BODINE ELECTRIC motor protection

Motor protection provides comprehensive protection for the motor, issuing alarms or triggering protective actions in case of overload, phase loss, stall, short circuit, overvoltage, undervoltage, leakage, three-phase imbalance, overheating, bearing wear, stator-rotor eccentricity, axial movement, or radial runout. The devices providing protection for motors are motor protectors, including thermal relays, electronic protectors, and intelligent protectors. Large and critical motors generally use intelligent protection devices.

BODINE ELECTRIC motor maintenance

Motor maintenance: 1. Before use, confirm whether the appearance of the low-speed motor is damaged and if there is any oil leakage. 2. Please confirm first whether the purchased low-speed motor specifications match the design. 3. If using accessories such as sprockets, pulleys, or speed reducers, install them according to relevant standards. 4. Lubricating grease is already filled in the low-speed motor housing, requiring no lubricant replacement for 16000 hours. 5. During the operation of the low-speed motor transmission, ensure that the current does not exceed the value indicated on the motor nameplate. 6. Please pay attention to ambient temperature, humidity, acidity, alkalinity, and other factors. 7. The applicable environment is -5°C to 40°C, with humidity below 85%, and indoor altitude below 1000 meters. 8. Incorrect installation, maintenance, or operation may cause severe damage to the low-speed motor. 9. When repairing or disassembling, strictly confirm that the external power supply to the motor is completely disconnected. 10. Safety protection devices must be properly installed to ensure absolute operational safety. 11. The motor must be grounded; please refer to relevant electrical distribution regulations. 12. Confirm that the motor is installed correctly before starting the low-speed motor. 13. If the low-speed motor is used with a variable frequency drive for low-speed transmission, an independent auxiliary cooling fan must be installed. 14. After a single-phase low-speed motor is powered off, residual charge remains in its capacitor; please discharge it first or ground the terminals. 15. For vertical motor installation, please specify in advance when ordering or contact our company.
