Features

1. High performance and low consumption
   2.5hp BLDC motor is a three phase electric motor, which especially suited for application requiring higher efficiency and power density.
2. Wide application range and good control effect
   Brushless dc motor works with a matching controller (RDDLZ-BD100) may achieve simple to complex control, turn from CW to CCW, and meet various communication requirements (RS232, RS485, CAN, etc.). BLDC controller can be controlled through 0-5VDC analog signal to adjust the speed.
3. Wide control speed torque range
   Brushless DC motor works with a gearbox (choose planetary gearbox with gear ratio from 4:1 to 200:1 or worm gearbox with gear ratio from 7.5:1 to 100:1) effectively reduce the motor's speed and moment of inertia to increase torque in your application, because the gearbox can control the start/stop and change speed in time.
4. Low noise and smooth operation
   Brushless DC motor has no brushes, no sparks will be generated during operation, which greatly reduces friction.
5. Good protection performance and continuous duty (24/7)
   1900W 48 volt BLDC motor kit adopts a new type of sealing device, which has good protection performance and strong adaptability to the environment, and works continuously in harsh environments such as corrosion and humidity.

Tips: Rotor Position Detector of BLDC Motor

The rotor position detector mounted on the motor shaft is an important part of the brushless DC motor. It determines the moment when the armature phase winding starts to energize. Its role is equivalent to the general brushless DC motor. Changing the timing (phase) of the position detector signal is equivalent to changing the position of the brush in space in the DC motor, which has a great influence on the characteristics of the brushless DC motor.

There are many types of position detectors, which usually include a stationary set of detector elements and a position signal generator that rotates with the rotor of the motor. In a position detector consisting of Hall elements, the Hall element is the sensing element, and the motor rotor pole itself is the position signal former. In other structures, such as electromagnetic induction, photoelectric, and proximity switches, a notched disk is often used as the position signal former. For example, in the photoelectric type, the gap is used to make the light irradiate the photocell to generate a signal. In the electromagnetic induction mode, the gap is used to change the magnetic circuit of the open transformer so as to generate the electromotive force in the detection coil.
