Of course, this type of motor controller cannot be used for more complex high-power Industrial applications. Along with these needs, motor controllers with more complete features have a more expensive commercial price. This paper showcases the simulation results of Hall sensors sequence matching concerning the speed of the BLDC Phase voltage sequence of the motor with load and no-load conditions. Hall effect sensors are the most commonly used method of detecting rotor position in BLDC motors, due to the low cost and as it is easy to use with the permanent magnets which are present in the rotor [3]. And the commutation happens every 60-degree increment, increasing the high-resolution sensing also, this DRV8312 hardware contains a low-side current sensing technique that is connected to the current sense element between the load and ground of the board. The major problem is to detect load short to ground and some system ground disturbance in the shunt resistor.
1. INTRODUCTION
1.1 Motor specification
In modern days, due to the rising popularity and demand for electric vehicles, these BLDC motors have gained a new platform to showcase their features. The popularity of Brushless DC motor (BLDC) is rapidly increasing due to their various advantageous features which include high density of torque, high density of power, high efficiency, good saliency ratio, flux weakening capabilities, and speed control operations over a wide range, etc [12]. However, the main challenge that occurs in the development of BLDC motor controllers always begins with the high complexity of the electronic commutation system that must be used because BLDC motors don’t have the commutator and brush compared to other DC motors [5,11]. So, it’s called a Brushless DC motor. There are many types of controllers that are commercialized at a lower price, one of them is DRV8312-EVM. This BLDC motor Controller has some features like torque control, speed control, etc., with a wider range of variables, and position control [1,2].
Every motor controller is built and driven based on the parameters of the motor which is used. So, the motor which is used here is a 24V BLDC motor with a maximum RPM of 3000. The output power of the motor concerning the maximum speed is 50W. And this motor is of 8 poles with the phase resistance of 0.7 Ohms and the maximum torque for this motor is 1.5Kg-cm.
continuous process. For example, BLDC motors have long been used in industrial applications such as feed drives for CNC machines, actuators, industrial robots, and electric vehicles have begun to use high-performance BLDC. There are specific BLCD motor control evaluation boards for analyzing these parameters and performance. One of the best-used evaluation boards is DRV8312-EVM from Texas instruments. Which contains C2000 real-time microcontroller. In this paper, the performance variation plots are superimposed with the rated parameter results to clearly understand the sensitivity and performance analysis of a BLDC motor through DRV8312 hardware. This provides a great way to learn and experiment with digital control of medium voltage brushless motors to increase the efficiency of operation for BLDC motors.
2. THEORY OF OPERATION DRV8312-C2 consists of a control CARD-based motherboard evaluation module. The DRV8312-C is a motor controller evaluation board for spinning a three-phase brushless DC motor (BLDC) often referred to as a permanent magnet synchronous motor (PMSM) [7,8]. The DRV8312-C is a highperformance, power-efficient, cost-effective sensorless fieldoriented control (FOC) and sensored or sensorless trapezoidal EMF commutation platform that speed test performance development for a quicker time to market through closed-loop proportional and integral error control of the motor [9,10].
The addition of, magnetic sensors, encoder sensors, current sensors, temperature sensors, voltage sensors, and signal amplifiers are the main component of this motor controller.
