Product Description:

Pacific Scientific designed the PMB33E-00114-00 servo motor. It is a component of the PMB Brushless Servomotors series. This motor is intended for demanding applications requiring precision, dependability, and high torque density.

The PMB33E-00114-00 brushless servomotor has a peak torque of 9.7 Nm (86.0 lb-in.) and a peak current of 10.6 A (Arms) during peak torque. It is designed to have a rated speed of 3000 rpm and a current of 5.3 A (Arms) at rated torque. Because of its high torque density, the motor's design reduces heating and improves efficiency. The motor has a shaft diameter of 9.52 ± 0.51 mm (0.375 ± 0.020 in). It comes with a variety of shaft options, including flat, round, square, and woodruff keys, making it ideal for a wide range of mounting applications. It has a rated voltage of 48 V DC and a maximum stall torque of 9.7 Nm (86.0 lb-in). This adaptability is aided by its NEMA Size 34 frame, which is compatible with industry-standard mounting systems. The motor has double-shielded bearings for increased durability and performance. Feedback is offered via a 26 AWG shielded cable (457 mm [18.0 in.] minimum length) and motor cable choices using 22 AWG shielded cable. It has adjustable features such as shaft seals and thermistors for added protection.

The PMB33E-00114-00 has an IP40 rating, making it appropriate for light industrial applications. The motor complies with global standards, including NEMA that ensures reliability in a wide range of industrial applications. The motor features winding types that are specifically developed to function with high-performance drives. Feedback options include a resolver, Hall sensor, or digital encoder, providing flexible control for a variety of applications. This motor is best suited for use in medical equipment, material handling, and semiconductor processing.
