1HP 3/4HP ECM BLDC motor for fan blower or Air source heat pump

Introduction

This page shows a high power EC/BLDC fan motor used in fan blower or air conditioner units and similar applications, which need to drive fan blowers.

Till now, Hengsheng has a various of specifications of AC BLDC motors, and different induction motor, geared motor, PM motor with gearbox. Because of its long working life, stable performance and low failure rate, our products are well received by customers. We have got the certification of CCC, RoHS and ISO9001:2008.

Features of BLDC motor

1. Rated Voltage:200-240V 50Hz/60Hz

2. Output power range: 750W

3. Speed 300-1500 adjustable

4. The driver adopts the structure of aluminum shell completely closed, which has high protection level and is safe and reliable.

5. The driver adopts independent installation structure, which is convenient for disassembly and maintenance after sale.

Application of AC/ BLDC Motor

How to check the quality of brushless DC motor

First, BLDC internal drive motor:

1. First carry out appearance inspection to observe whether the motor is worn and bumped.

2. Detect the impedance and voltage drop values of each lead end.

3. Supply voltage to the BLDC motor for operation test, under normal circumstances, it is necessary to provide low starting voltage and rated voltage, respectively to detect whether the motor can start normally in the two states, and whether the generated current, voltage, power, speed and other parameters are within the qualified range.

4. Use motor detection instruments for load testing, apply load to the BLDC motor, simulate the normal working conditions of the motor, and detect parameters such as voltage, current, and speed

5. Detect whether there is noise and abnormal sound during the operation test of the motor under the rated voltage.
