How DC bus voltage is related to speed and torque in DC, BLDC and BLAC motors?
Three important variables of any driver design are the bus voltage to be used, the maximum torque and speed requested. These variables are not independent and are mutually connected. This means that depending on the provided bus voltage, the maximum ...
Understanding why the motor phase current is different to the power supply currents
The motor current is lower than the dc current because the servo drive behaves as a step-down DC/DC converter. Ignoring inefficiencies, commutation and commutation details (see below), the product of "input voltage x input current" should be equal to ...
How to manually execute a profile torque movement by using the registers
In this How-to guide, we will explain how to execute a movement (profile torque) by directly changing the register values, instead of using MotionLab or the dedicated macros for motion. We will consider a movement towards a specific torque in this ...
How to dimension a power supply for an Ingenia drive
In this How-to guide we will show you how to properly dimension the power supply that you need in your system. Choosing an appropriate power supply is an important step for a successful motion control system solution. The choice of a power supply is ...
How to tune a stepper motor
In this How-to guide, basic steps for the tuning of a stepper motor are explained. The main objective is to point out the main differences between tuning of a 'normal' actuator and a stepper actuator. Knowledge about tuning and how to use MotionLab ...
