Choosing the right turnstile motor requires evaluating torque, RPM, 전압, 능률, and control strategy based on the application. BLDC motors are typically preferred for modern turnstiles due to higher efficiency, 더 긴 수명, and smoother motion control, while brushed motors may be used in cost-sensitive systems. Key selection factors include required torque for barrier movement, 회전 속도 (RPM), voltage compatibility (typically 24V–48V), and system integration with controllers. Proper motor sizing ensures reliable operation, 유지 보수 감소, and optimal lifecycle cost.
Turnstile systems are critical components in access control infrastructure, used in metro stations, 사무실 건물, 경기장, 산업시설. The motor is the core actuator that determines system performance, 신뢰할 수 있음, and user experience. For engineers, OEM designers, and procurement managers, selecting the correct motor is not simply about power rating—it requires a detailed understanding of torque requirements, speed profiles, electrical constraints, 및 제어 아키텍처.
This engineering guide explains how to choose a turnstile motor with a focus on torque calculation, RPM selection, voltage compatibility, and real-world application considerations. It is designed to support both technical decision-making and B2B procurement.
What Is a Turnstile Motor and Why It Matters?
A turnstile motor is the electromechanical component responsible for driving the rotation or movement of barriers in access control systems. It converts electrical energy into controlled mechanical motion, enabling smooth and secure passage of individuals.
Key Functional Roles
- Drive barrier rotation or swing motion
- Control opening and closing speed
- Provide holding torque for locking positions
- Ensure smooth and safe user interaction
The motor directly affects throughput efficiency, 소음 수준, 내구성, 유지보수 빈도. Poor motor selection often leads to issues such as jerky movement, 과열, 아니면 조기 실패.

How to Calculate Required Torque for Turnstile Motor
Torque is the most critical parameter when selecting a turnstile motor. It determines whether the motor can overcome inertia, friction, and external loads.
Torque Calculation Formula
토크 (티) = Force × Radius
어디:
- Force = resistance from barrier weight and friction
- Radius = distance from rotation center
Engineering Considerations
- Barrier weight and length
- Friction in bearings
- Safety margin (typically 1.5–2x)
예를 들어, a heavy glass swing gate requires significantly higher torque than a lightweight tripod turnstile.
How to Determine RPM for Turnstile Applications
RPM (rotations per minute) defines how fast the turnstile operates.
Typical RPM Range
- Tripod turnstile: 10–30 RPM
- Swing gate: 20–60 RPM
- Flap barrier: 30–100 RPM
Speed Considerations
- User comfort
- Safety regulations
- Throughput requirements
Excessive speed can compromise safety, while low speed reduces efficiency.
Voltage Selection: 24V vs 48V vs Higher Systems
Voltage affects system efficiency, current consumption, and wiring design.
Common Voltage Options
- 24V DC – standard for most systems
- 48V DC – higher efficiency, 낮은 전류
- 72V+ – high-power industrial systems
Engineering Trade-offs
- Higher voltage → lower current → less heat
- Lower voltage → safer but higher current
Many modern turnstiles use 24V or 48V BLDC motors.
