Product Description:

The PMB brushless servo motor is designed and manufactured by Pacific Scientific for applications where precise motion control is essential. The PMB33E-00216-02 brushless servo motor belongs to the series of PMB brushless servo motors.

The motor has a peak rated torque of 9.7 Nm. A secure electrical contact is provided by the connector arrangement, which consists of flying leads with MS connectors. The peak stall torque is 9.7 Nm and the continuous stall torque is 4.9 Nm, therefore permitting the motor to meet high-demanding torque requirements. The shaft is flat, so that a secure mechanical coupling is possible. The PMB33E-00216-02 brushless servo motor can deliver a continuous rated torque of 4.4 Nm. The customization code has a PTC thermistor for thermal protection. The stack length is defined as a stack length multiple that contributes to torque output and motor dimensions. The entire construction and specifications make the motor suitable for all precision-driven industrial automation applications. The NEMA Size 34 frame ensures compliance and compatibility with the standard mounting configurations. The digital encoder that is incorporated into the motor is equipped with communication capabilities. Additionally, the encoder has a resolution of 4096 ppr, which enables positional control systems to get precise position feedback.

The frame size design ensures mechanical compatibility with the standardized configuration of equipment. The stack length design ensures a reasonable shaft length that can support the required torque without requiring a large footprint. The digital encoder allows for precise positional synchronization between commanded and actual positional locations. The PMB33E-00216-02 brushless servo motor connector type ensures unified signal integrity. The shaft design increases the power transmission efficiency. The rated winding current ensures consistent torque delivery for the application.

Frequently Asked Questions about PMB33E-00216-02:

Q: Why does PMB33E-00216-02 include a PTC thermistor customization code?

A: The PTC thermistor provides temperature monitoring inside the motor. It helps protect windings and insulation from heat damage during extended or high-load usage.

Q: How does PMB33E-00216-02 use flying leads with MS connectors?

A: The flying leads with MS connectors ensure secure and adaptable wiring. They allow reliable signal transfer between the motor and control systems.

Q: Does PMB33E-00216-02 achieve accurate control with its digital encoder?

A: Yes, the 4096 ppr digital encoder provides precise feedback. This enables accurate synchronization between commanded and actual rotor positions for consistent motion profiles.

Q: Why does PMB33E-00216-02 have a flat shaft design?

A: The flat shaft design improves torque transfer. It reduces slippage between the shaft and coupling for more reliable mechanical performance.

Q: How does PMB33E-00216-02 use a stack length multiple?

A: The stack length multiple determines the magnetic and torque capacity. It influences the motor’s power output without increasing overall diameter dimensions.
