If you're looking to design a security camera system, there are a lot of factors to consider. One of the most important things to look for is a reliable motor.Surveillance camera DC brushless motors are a great choice for a number of reasons, including their precision movement and quiet operation. Let's take a closer look at why you should consider this type of motor for your next project.Surveillance cameras and photo equipment require precise movements to capture accurate images and footage. Brushless motors can provide these motions quickly and easily, allowing for quick response times and quiet operation.
TI offers a wide selection of high-performance brushless motor drivers that deliver the precision movement needed for surveillance camera applications. These devices incorporate sensored solutions that use encoders, resolvers, or Hall-effect sensors to detect the position of the rotor relative to the stator at all times for efficient commutation.These motor drivers also offer sensorless-FOC control that allows users to identify, tune, and fully control motor parameters through real-time 3-phase voltage and current monitoring. This enables developers to quickly and easily tune a motor while delivering consistent system performance, regardless of motor manufacturing variations.
These motors are commonly used in pan-tilt-zoom (PTZ) and drone cameras, as well as unmanned aerial vehicles (UAVs). They can provide precise movement with low noise, allowing for quiet stealth operations.Quiet operation is one of the most important factors to consider when choosing a motor for your surveillance camera. A quiet motor can help to reduce the amount of noise that could alert or disturb your subjects, and it can also prevent the motor from wearing down quickly.
Brushless DC motors, as their name suggests, are electrically driven and have no brushes or moving parts to worry about. Instead, the rotor consists of a permanent magnet ring and the coils are stationary.Because they are more simple, brushless DC motors can be designed with greater symmetry and reduce vibration and noise by controlling the overall design of the rotor and stator.
TI’s DRV10x family of motor drivers include trap, sine and FOC control variants to minimize noise and vibration in a variety of motor applications. They feature 180-degree pure sinusoidal, sensorless algorithms that are up to 75 percent quieter than the competition and eliminate annoying clicks or pops at start-up.Surveillance cameras require high precision and control, and brushless motors help enhance that quality. They can also extend the lifespan of your security system by providing you with a longer operating time and minimal maintenance needs.
