The best motor for turnstile systems depends on performance, Độ bền, and control requirements. For modern OEM turnstile manufacturers, BLDC motors are typically the optimal choice due to their high efficiency, Kiểm soát chính xác, tuổi thọ dài, và bảo trì thấp. Tuy nhiên, brushed DC motors and servo motors are still used in cost-sensitive or high-precision applications. Selecting the right motor requires evaluating torque, tốc độ, Vôn, control method, and duty cycle to match real-world operating conditions.
What Motor Is Used in Turnstile Systems?
Turnstile systems rely on controlled rotational motion to regulate pedestrian access. The motor serves as the core actuator, converting electrical energy into mechanical torque to drive the barrier arm or gate. The most commonly used motor types include BLDC motors, động cơ DC chải, và động cơ servo, each offering different performance characteristics.
In traditional systems, brushed DC motors were widely used due to their simple structure and low cost. Tuy nhiên, modern smart turnstiles increasingly adopt BLDC motors because they offer higher efficiency, Nhịp cuộc sống dài hơn, and better integration with electronic control systems.
Servo motors are typically used in high-end applications where precise positioning, Chuyển động trơn tru, and dynamic control are required, such as speed gates in airports or metro systems.
