What is a Motor Driver?

A driver is an electrical circuit that enables switching the current into a motor's winding in different ways in order to produce the desired speed and torque.

At Mechtex we provide a variety of Motor Drivers in both conventional and customized forms. The two most popular types of drivers are BLDC and DC motor drivers. These drivers are used in a wide range of applications, from as small application as miniature toys to the heavy industrial machinery.

Why are motor drivers necessary when plug-and-play would do?

All electric motors operate primarily on alternating current, even DC and stepper motors. The mechanisms of all moving objects are controlled by the four universal Maxwell electromagnetic laws. The conclusion of these laws, specific to motor application, can be summarized as follows:

  1. A change in electric current produces magnetic field
  2. A change in magnetic field induces current in conducting cable.
  3. Take any dummy motor, like the one in your table or ceiling fan. Rotating the fan’s blade manually causes current to flow into the winding. The reverse of the same phenomenon occurs in a table or ceiling fan when electric current passes through the motor. 

Why are there so many different kinds of drivers? 

To meet the needs of your industry, Mechtex BLDC and Stepper Motor drivers can be made to any size and specification. Just give us a call to go through the details of your application. Designing an electric driver that can operate wide varieties of electric motor is not practical. Motor drivers are specifically designed by manufacturers for specific type of applications. At Mechtex, we can help you choose a compatible motor driver for your needs.

There are several easy-to-use drivers available for DC, BLDC, and stepper motors. A servo driver, on the other hand, needs to be chosen with greater care.

Technological Advances - Ease of use

There are several different drivers available to control the motors, including automatic speed control, automatic torque control, sensor-based, and senseless drivers. The amount of charge and concentration of current applied to a motor winding can be adjusted to regulate any form of rotational dynamics of a mechanically stable motor by electric driver.

System engineers and End Users can achieve the appropriate level of performance with little to no knowledge of Mechatronics engineering thanks to programmable controllers and cutting-edge user interfaces currently on the market. The speedometer-like screen, practical knobs, and user-friendly UIs make it possible for users to control the speed and remotely monitor the system, ensuring the safety of small- and large-scale operations.
