Product Description:

The PMB33C-10114-02 Brushless Servo Motor features an 8 pole synchronous design and neodymium iron boron magnets for maximum torque output. The motor offers precise digital encoder feedback, high efficiency and reliable operation.

This Pacific Scientific PMB33C-10114-02 brushless servo motor delivers a torque constant of 1.86 Nm/A_RMS. This enables efficient torque generation with minimal current draw. Its continuous stall current is rated at 2.9 A that supports extended operation without overheating. The motor provides a typical rated torque of 4.84 Nm when operated at 240 V AC or a 320 V DC bus. Its voltage constant (line to neutral) is specified at 1.11 V_RMS/rad/sec. The thermal resistance of the motor is 0.78 C/W. This ensures effective heat dissipation during sustained loads. The maximum static friction of the model is 0.169 Nm. It includes a digital encoder with commutation signals. The encoder offers 2048 pulses per revolution for precise speed and position feedback. The motor’s thermal design supports continuous duty cycles without compromising performance. The motor’s construction meets IP40 standards. This rating provides protection against solid objects larger than 1 mm. The motor is equipped with a Positive Temperature Coefficient (PTC) thermistor for real time temperature monitoring. This thermistor is designed to detect temperature changes within the motor's internal components. The resistance of the PTC thermistor increases with temperature as the motor operates and generates heat.

This PMB33C-10114-02 brushless servo motor is built in a NEMA 34 frame size with a round shaft profile for compatibility with various mechanical couplings. The electrical connections of the model are facilitated via flying leads with AMP connectors. The servo motor is engineered for applications requiring precise positioning, consistent torque and smooth operation.
