1000 Series Brush DC Servomotor


Design Features

  • Dynamically balanced, skewed rotor for exceptionally smooth velocity
  • Standard NEMA 23, 34, and 42 frame sizes
  • Standard stainless-steel shaft resists corrosion
  • Double shielded bearing for long motor life
  • Options include tachometer, encoders, metric flange, and integral cable

The 1000 series motors are Aerotech’s high-performance brush-type rotary DC servomotors. These motors are designed for a variety of general and high-performance motion control applications. Custom mechanical or electrical configurations are also available with minimal lead time.

Skewed Rotor

The 1000 series DC motors feature a dynamically-balanced skewed rotor and tachometer assembly for less cogging and smoother velocity control. The skewed laminations help reduce the effects of torque ripple that can cause velocity disturbance. The result is a much smoother velocity profile for such applications as machine tool, medical, semiconductor, and scanning.

Standard NEMA Frames

The 1000 series motors come in standard NEMA frame sizes including 23, 34, and 42. The standardized flange and shaft dimensions make it easy to mount to existing NEMA-based machines.

Each motor is constructed from high-grade materials including a stainless-steel shaft, double-shielded bearings, and precision machined housing. Full burn-in of each motor ensures long-term reliable operation.

Wide Torque Range

The 1000 series DC motors cover a wide range of torque to meet virtually all high-end DC motor applications. Continuous output torque ranges from 0.25 N·m (35 oz·in) to 1.48 N·m (210 oz·in). Peak output torque ranges from 1.84 N·m (260 oz·in) to 7.1 N·m (1000 oz·in).

Customized Applications

Standard motor models are available with and without a DC tachometer in different voltage constants. Options include alternative windings, metric shafts and flanges, encoders with line driver or amplified sine-wave output, rear housings with integral cables, or MS-style heavy-duty connectors.

Integration (Required)

Aerotech offers both standard and custom integration services to help you get your system fully operational as quickly as possible. The following standard integration options are available for this system. Please consult Aerotech if you are unsure what level of integration is required, or if you desire custom integration support with your system.

Option Description
-TAS Integration - Test as system
Testing, integration, and documentation of a group of components as a complete system that will be used together (ex: drive, controller, and stage). This includes parameter file generation, system tuning, and documentation of the system configuration.
-TAC Integration - Test as components
Testing and integration of individual items as discrete components that ship together. This is typically used for spare parts, replacement parts, or items that will not be used together. These components may or may not be part of a larger system.
