Product Description:

The PMB33E-00100-00 is a brushless servomotor manufactured by Pacific Scientific for the PMB Brushless Servomotors series. Within automated assembly cells or packaging lines, this motor supplies closed-loop rotary motion so position, velocity, and torque remain tightly regulated by the drive electronics. Its electromagnetic stack and resolver feedback allow rapid command changes while the rotor follows the requested profile with stable response and accurate repeatability. Because commutation remains electronic, the motor can support smooth low-speed motion as well as rapid acceleration during short cycle tasks. That behavior is useful on indexing axes that must start, stop, and reverse quickly without losing commanded position.

The frame is built to the NEMA Size 34 envelope, so it fits machinery already drilled for that bolt circle. Continuous stall operation at a rated current of 7.4 ARMS on a 240 VAC supply indicates the drive output required when the shaft is locked but energized. Power and feedback leave the housing through flying leads with AMP connectors, which removes the need for separate field-crimped plugs. The leaded connection style also gives cable routing flexibility where rear connector clearance is limited by surrounding machine parts. Rotor position is measured by a resolver, giving analog sine and cosine signals that remain reliable in electrically noisy environments. A flat on the shaft provides a positive interface for couplings or pulleys without using a keyway.

The laminated core uses a stack length multiple of 3, which supports higher continuous torque without increasing the flange dimensions. The longer active iron length increases magnetic interaction in the stator and rotor, which helps raise torque capacity for its frame size. Because the unit is delivered as a standard motor, its windings, connectors, and hardware follow the normal production configuration for this model. The designation PMB Series Brushless Servomotor links the motor to compatible drives in the same family and keeps electrical matching straightforward. This helps the motor work with established control hardware that uses the same feedback and commutation method.
