Features

1. High performance and low consumption
   3.8 kW brushless DC motor is three phase electric motor, which especially suited for application requiring higher efficiency and power density.
2. Wide application range and good control effect
   BLDC motor works with a matching controller (RDDLZ-KBL) 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 inline gearbox or right angle gearbox with gear ratio from 3:1 to 200:1) 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)
   5 hp 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: Different Working Principle between BLDC Motor and Stepper Motor

BLDC motor
The BLDC motor uses semiconductor switching devices to realize electronic commutation, that is, it uses electronic switching devices to replace traditional contact commutators and brushes. The brushless dc motor has the advantages of high reliability, no reversing sparks, low mechanical noise, etc., so it is widely used in high-end audio recorders, video recorders, electronic instruments and automated office equipment.

Stepper motor
Nema stepper motor is based on the principle of electromagnets to convert electrical energy into mechanical energy. It is driven by coils wound on the slots of the motor stator. The biggest difference between a stepper motor and other control motors is that the stepper motor can receive digital control signals (electric pulse signals) and convert them into corresponding angular or linear displacements. It is actually an executive element that completes digital mode conversion. Moreover, it can be open-loop position control. Input a pulse signal to get a prescribed position increment.
