- Brief Introduction
Brushless DC Electric Motor (BLDCM) overcame the congenital defects of Brushless dc Motor and replaced mechanical commutator with electronic commutator.
- Product Features
Brushless DC Electric Motor Drives overcome the congenital defect of a Brushless dc Motor, with electronic commutator replaces the mechanical commutator, so both Brushless dc Motor has the characteristics of dc Motor performance of speed adjustment, but also has ac Motor has simple structure, no commutation spark, reliable operation and easy maintenance, etc.
Brushless DC Electric Motor Drives is the essence of dc power supply input, the use of electronic inverter to direct current into alternating current, rotor position feedback three-phase ac permanent magnet synchronous motor.
- Scope of using
The Brushless DC Electric Motor Drives exchanges the stator and rotor of a common DC motor. The rotor generates an air gap flux for the permanent magnet: the stator is an armature, and the multiphase winding constitutes a DC motor. Structurally, it is similar to a permanent magnet synchronous motor.
- Product Specifications
The Brushless DC Electric Motor Drives includes a power supply unit and a control unit: the power supply unit supplies three-phase power to the motor, and the control unit converts the input power frequency according to requirements. The power supply unit can be directly connected to the DC input (usually 24V) or AC input (110V/220 V).
If the input is AC, it must be converted to DC by the converter. Whether the Brushless DC Electric Motor Drives input or the AC input is to be transferred to the motor coil, the DC voltage must be converted from an inverter to a 3-phase voltage to drive the motor.
- Direction for Using
Continuous load application: mainly refers to the field that requires a certain speed but does not require high speed accuracy, such as fan, pump, blower and other applications, such applications cost less and are mostly open loop control.
Variable load application: Brushless DC Electric Motor Drives is the speed needs to change in a certain range of applications, Brushless DC Electric Motor Drives speed characteristics and dynamic response time characteristics have a higher demand. Such as household appliances, dryers and compressors are a good example, the automotive industry in the field of oil pump control, electrical controller, engine control, such applications of the system cost is relatively higher.
- Usage Support
In order to further understand the defects in motor operation, check test can be done before disassembly if possible. For this purpose, the Brushless DC Electric Motor Drives with load test run, detailed inspection of each part of the motor temperature, sound, vibration and other conditions, and test voltage, current, speed, and so on, and then disconnect the load, a separate no-load inspection test, measurement of no-load current and no-load loss, make a record.
