Product Description:
The Brushless Motor PMA43Q-Y0100-02 by Pacific Scientific is designed for high-reliability motion systems and precise performance. With a frame size of 115 mm square, this motor has a compact and efficient form factor ideal for high-performance automation applications.
This brushless motor provides a continuous stall torque of 6.1 Nm to provide steady force in prolonged load operations. For demanding, dynamic operations, the PMA43Q-Y0100-02 motor provides a maximum torque of 21.7 Nm with a current rating of 28.8 Arms. This high torque-to-current ratio allows optimal output with effective power usage under maximum loads. This brushless motor’s torque constant is 0.85 Nm/Arms (RMS) to help in controlled torque generation in actual use. This motor’s electrical connector interface is 6PP, 12PSO, which provides secure connections and broad drive system compatibility. The line-to-line inductance of this motor is 5.3 mH to provide stable electrical performance with minimal ripple and improved responsiveness to the system. With a thermal resistance measured at 0.59 °C/Watt, this motor has efficient heat dissipation and provides continued performance when continuously operated. With a built-in resolver sensor, this motor provides accurate rotor position feedback and durability in demanding environments.
The rotor of this motor incorporates Neodymium-iron-boron magnets, which provide high magnetic strength with enhanced torque density without an increase in motor size. The shaft length of the PMA43Q-Y0100-02 motor is 40 mm, and it accommodates a broad variety of mechanical couplings and drive train arrangements. This motor’s static friction is only 0.15 Nm, which allows easy startup and minimal energy loss during standstill. The viscous damping coefficient of this brushless motor is 0.05 Nm/kRPM to achieve better dynamic stability and lower mechanical oscillation. The construction of this motor is robust TENV (Totally Enclosed Non-Ventilated) with an IP65 protection rating, which provides resistance to dust and water entry.
Frequently Asked Questions about PMA43Q-Y0100-02:
Q: Why is a resolver sensor used in the PMA43Q-Y0100-02 motor?
A: Resolver sensors provide robust position feedback and resist electrical noise, ideal for industrial settings. They maintain accuracy even under high vibration or temperature changes.
Q: How does the neodymium-iron-boron magnet benefit the rotor design?
A: These magnets deliver high magnetic strength with low volume. This enhances torque output without increasing motor dimensions.
Q: Why is the PMA43Q-Y0100-02 equipped with a TENV housing?
A: The Totally Enclosed Non-Ventilated (TENV) design protects internal parts from contaminants. It also allows the motor to operate reliably in dusty or moist environments.
Q: What role does the 5.3 mH inductance play in motor operation?
A: It helps smooth current flow and reduce torque ripple. This is essential for achieving consistent motion control.
Q: How does the 0.05 Nm/kRPM damping coefficient improve stability?
A: It reduces mechanical oscillations during acceleration or deceleration. This supports smoother speed transitions under load.
