Product Description:

The PMB33C-00114-03 is intended to work reliably and regulate motion precisely in tough industrial settings. This type is based on a NEMA Size 34 frame, which gives it a strong and small footprint that works with many different system designs. The motor is designed for tasks that need constant, regulated movement and great positional precision. It has a rated speed of 950 RPM. The PMB33C-00114-03 weighs 6.3 kg (13.8 lbs) and is built to last. It uses neodymium-iron-boron magnets to maximize torque production and make the motor more efficient overall. Its 8-pole synchronous construction makes sure that the torque is always the same, and its IP40 protection grade keeps out dust and solid objects, making it safe to use in clean, regulated situations.

|One of the best things about this motor is that it has a built-in digital encoder for commutation, which makes it easy for the motor controller to get precise feedback on both position and speed. This makes sure that current automated systems work smoothly. The encoder sends sine and cosine output signals, including 1024 cycles per revolution and an extra signal with one cycle per revolution, enabling precise control. The motor has an 18-inch lead that works with both MS-type and AMP small Mate-N-Lock® connections, making it easier to install and add to systems that are already in place.

The PMB33C-00114-03 is designed to work with Pacific Scientific's sophisticated motor drives and controllers at a maximum bus voltage of 240V AC or 320V DC. It can endure cycles of high-torque demand since its performance envelope encompasses both continuous and intermittent duty zones. However, the RMS system torque must stay within safe continuous duty limits.
