Advantages of Gearheads:  What to Choose and Why

We know that the purpose of a motor is to provide a certain amount of power to produce a specified amount of speed and torque. In applications requiring a large torque load at slow speeds, it is more economical to use a gear motor (aka gearhead) rather than a large enough motor to provide the specified torque. The gearhead  is mounted on the front end of the motor and specific gearing provides the overall speed and output torque. There are various types of gearhead technologies. Here, we will focus on Spur compound and Planetary.   Spur gears are designed with the concept of having only one transmission point per train.

How Encoders Provide Motor Speed and Position Control 

In many mechanical systems, precise motion hinges upon effective monitoring and control of the motor. Encoders make motion control possible by sensing the motor’s speed and position and sending feedback signals to control components. Two square waves, or channels, shifted 90 electrical degrees from each other, along with an optional index pulse that occurs once per revolution, encode the angular position data.

How to Optimize Your Product or Device Output

Early engagement with an Application Engineers (AE) can be a valuable first step when working on your application design and looking for the optimal motion solution. Our AEs will gather valuable information during the motor selection process, to ensure that they use the right motor for the allotted space and application.  After a thorough analysis and discussion, they can provide speed/torque curves for various motor options. If they know the duty cycle, they can help to determine whether or not to use a smaller motor in a temporary overdrive application.

Driving DC Brushed Motors

To control a DC motor, a variable, and controlled power supply is needed. There are three types of methods that can be used:         

    • Voltage-controlled linear supply
    • Current linear supply
    •  PWM (Pulse Width Modulation)

Why An Encoder?

Posted by Chris Schaefer   Jun 16, 2020

Encoders provide feedback for accurate control of speed and positioning. The rotor angular position is given through two square waves 90 degrees shifted and an optional index pulse occurring once a revolution. There are multiple technologies to get these results.
