ターンスタイルモーターの選び方 (トルク, 回転数, 電圧ガイド)
注目のスニペット:
Choosing the right turnstile motor requires evaluating torque, 回転数, 電圧, 効率, and control strategy based on the application. BLDC motors are typically preferred for modern turnstiles due to higher efficiency, 長寿命, and smoother motion control, while brushed motors may be used in cost-sensitive systems. Key selection factors include required torque for barrier movement, 回転速度 (回転数), voltage compatibility (typically 24V–48V), and system integration with controllers. Proper motor sizing ensures reliable operation, メンテナンスの軽減, and optimal lifecycle cost.
Turnstile systems are critical components in access control infrastructure, used in metro stations, office buildings, スタジアム, and industrial facilities. The motor is the core actuator that determines system performance, 信頼性, and user experience. エンジニア向け, OEMデザイナー, 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, and control architecture.
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, 騒音レベル, 耐久性, and maintenance frequency. Poor motor selection often leads to issues such as jerky movement, 過熱, または早期の失敗.

Types of Motors Used in Turnstiles
Several motor types are used in turnstile systems, each with unique characteristics.
1. BLDCモーター
- 高効率 (85–92%)
- 長寿命
- 正確な制御 (FOC)
2. ブラシ付き DC モーター
- 低コスト
- シンプルな制御
- High maintenance
3. ステッピングモーター
- High positioning accuracy

Modern systems increasingly favor BLDC motors due to performance and reliability advantages.
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
トルク (T) = Force × Radius
どこ:
- 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)
例えば, a heavy glass swing gate requires significantly higher torque than a lightweight tripod turnstile.
How to Determine RPM for Turnstile Applications
回転数 (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.
電圧の選択: 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, より低い電流
- 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.
