Product Description:
The Pacific Scientific's PMB33E-10101-01 is a precise motion control motor that has a Resolver-based feedback system, resilient to hostile environments and stable even in electrical noise. This servo motor comes with a round shaft and a shaft seal to offer protection against the entry of dust and liquid into the assembly, and improves its life in moderately protected atmospheres.
The steady stall torque of 5.42 Nm enables this motor to sustain torque output without overheating under continuous load and makes it suitable for moderate steady-state torque applications. This PMB33E-10101-01 brushless motor also has a torque constant of 0.93 Nm/Arms to provide effective current-to-torque conversion, which leads to energy-saving operation for dynamic load cycles. This servo motor’s stall current at constant operation is 5.8 Arms, which makes it compatible with industrial servo drives and power modules. This motor’s inertia is 0.404 ×10⁻³ kg·m², which yields a dynamic profile that enables rapid acceleration and deceleration. The viscous damping coefficient of 0.038 Nm/kRPM further aids in the damping of this motor’s oscillations and yielding smoother velocity control. The 32 minutes of thermal time constant means this brushless motor provides efficient heat dissipation for prolonged operating cycles with less risk of overheating.
The PMB33E-10101-01 motor accommodates installation up to a maximum height of 1000 meters above sea level and provides operation without derating at normal atmospheric conditions. With eight magnetic poles, this brushless motor provides stable magnetic flux distribution and enhanced torque development, particularly at low speeds. The PMB33E-10101-01 servo motor has a rated speed of 3,000 RPM when driven from a 320V DC bus, supporting high-speed movement in servo-driven mechanisms. This motor is designed to function at a line-to-line resistance of 2.2 Ohms for promoting maximum energy efficiency and reduced power loss. This brushless motor is built with IP40 protection, which makes it ideal to be used in clean, protected enclosures.
Frequently Asked Questions about PMB33E-10101-01:
Q: Why does the PMB33E-10101-01 use a resolver instead of an encoder?
A: Resolvers provide noise immunity and durability in harsh environments, ensuring stable position feedback. They’re ideal for industrial setups with high electrical interference.
Q: What role does the 8-pole design play in motor performance?
A: It improves torque ripple control and delivers smoother operation at lower speeds. This enhances performance in applications requiring fine positioning.
Q: How does the low rotor inertia of 0.404 ×10⁻³ kg·m² benefit this motor?
A: Low inertia allows quick response to command inputs, enabling fast acceleration and deceleration. This makes it suitable for high-speed servo systems with frequent directional changes.
Q: What advantage does the 32-minute thermal time constant offer in PMB33E-10101-01?
A: It ensures the motor can operate under load for extended periods without rapid overheating. This is useful in long-duration industrial tasks.
Q: How does the 0.038 Nm/kRPM viscous damping coefficient affect motion?
A: It helps dampen oscillations during speed transitions, improving velocity control stability. This minimizes mechanical wear in repetitive motion cycles.
