Unmatched Ruggedness and Cost Effectiveness in a Comprehensive Family of Brushless Servomotors
Pacific Scientific's new wide voltage range (from 240 to 480V ac) PMA Series is the industry's most rugged, comprehensive line of reliable, customizable and cost-effective brushless servomotors.
Rugged construction earns IP67 rating (on selected models) and enhances your equipment reliability. CE compliance and medium-voltage capability open the door to a world-wide range of applications making the PMA Series the ultimate cost-effective choice for your motion control needs.
This line extends Pacific Scientific's commitment to
offering you the highest performance products, backed by unmatched
customer support and quality, with an ability to offer custom products
to fit your unique applications.

Pacific Scientific's PMA Series is industry's most rugged,
comprehensive line of cost-effective brushless servomotors available.
Now, with the addition of the new PMA1 series motors, the family gets
bigger - and smaller. These compact motors feature a 55 mm square
frame, in three stack lengths. A continuous rated torque range from
0.21 to 0.6 Nm, optional sealing to IP67, CE compliance and the
capability of integral parking brake give these motors the flexibility
to meet your application. This motor family extends Pacific
Scientific's commitment to offering you the highest performance,
backed by unmatched quality and customer support, tailored to your
applications.
In designing the PMA1 Series, Pacific Scientific engineers analyzed real-world motion control applications and tailored the windings for maximum efficiency using matched PC832, SC902 and SCE902 drives. The combination of Pacific Scientific motors and drives results in higher performance and efficiency, delivering more usable torque in your application.

Dimensions
In the table below, we show the performance data for the recommended combinations of PMA1 motors and PC832, SC902 or SCE902 drives. In addition to continuous stall current (ICS), inertia (J) and line-line inductance (L), each system has ratings provided that enable you to construct a reference chart to compare and size systems. The ratings required to construct the chart are:
- Peak Stall Torque (TPS)
- Peak Rated Torque (TPR)
- Continuous Stall Torque (TCS)
- Continuous Rated Torque (TCR)
- Rated Speed (WR)
- Unloaded Motor Speed (WNL)
To construct a chart, plot the points as shown in the example. Note that the chart provides continuous and intermittent duty zones. Systems can be operated continually at torque/speed combinations anywhere in the continuous duty area, assuming the ambient temperature is less than 40°C. Operation in the intermittent duty zone must be limited to a duty cycle, which will produce an RMS system torque falling within the continuous duty area. The RMS torque value is defined by the magnitude of the intermittent torque and the percentage of time spent at that torque.
