subject: Important Considerations to Choose Specific DC Drives [print this page] A DC drive acts as an interface between the motor and the controller and is used in numerous applications. For different applications, there is need to choose industrial DC drives with different specifications. Learn about some important considerations that must be taken into account to choose the right DC drive.
Design Features
A compact design DC drive should be chosen if you have less space for its intallation. Next, you must choose a DC drive which is simple to install and use. A drive with quick and simple startup should be given the preference. Finally, the drive should be easy to integrate with the existing environment of the industrial setup.
Types of DC Drives
Adjustable speed control Industrial DC drives are the most common ones. A non-regenerative DC drive is one that controls the speed and torque of motor in one direction only. These drives are simplest in operations and have been used for many years. A regenerative DC drive is one that apart from controlling the speed of motor rotation also controls the direction of motor torque.
There are brushed and brushless DC drives as well that are suitable to work in conjunction with brushed and brushless DC motors respectively. Servo control and integral motion control drives are other options. Consult an expert and choose the right type of DC drive.
Loop Control
There are electric DC drives with open loop control that uses tachometer to monitor the speed of the motor. On the other hand, a closed loop control DC motor uses force, position or other feedback to control the speed of the motor.
Power Efficiency
One of the most important considerations to choose industrial DC drives is the power efficiency of these drives. Consider the input range and output range f the DC drive to make a good choice. A less power consuming DC drive should help you save cost.
Other Specifications
Maximum or no-load speed of DC drives is another specification worth considering. Besides, bandwidth and switching frequency are other important factors that should be taken into account. You may also consider noise immunity too as the deciding factor. Finally, consider a DC drive which is affordable as well as a cost-effective solution for long term. DC drives should be purchased on the basis of the considerations discussed above. Also, choose a reputed manufacturer and dealer to buy these useful industrial drives.
