Baldor Launches DSM Series Integrated Stepper Motor/Drive

Baldor Electric Co. (UK) launched a new range of micro-stepping motors with onboard drive electronics, the DSM Series, which are well suited in instrumentation, test, medical devices and machinery adjustment applications. There are three frame size choices for the DSM Series, each in three motor lengths, offering a choice of nine torque ratings spanning 32 oz-in to 1,061 oz-in.

The three choices of Baldor DSM motor/drives have NEMA frame sizes of 17, 23 and 34. Each frame size can also be selected with one, two or three winding stacks, which provides developers with a choice of holding torque ratings of 32 oz-in, 60 oz-in, 74.9 oz-in, 90 oz-in, 144 oz-in, 239 oz-in, 381 oz-in, 575 oz-in or 1061 oz-in. Users can also select from a number of configuration options to optimize the motor/drive for an application, including single or dual shafts, with optical encoder or control knob, and flying lead or connector interface.

The 1.8° stepping motor can be configured for operation in any of 14 step sizes from one-half to 256 microsteps per full step, using a Windows utility and a motor-to-PC set-up cable. The chosen setting is stored in non-volatile memory, and may also be modified on-the-fly by the motion controller if required. Baldor supports the new motor drives with its NextMove range of motion controllers. These offer developers the option of PCB modules for system integration in Eurocard or PCIbus form-factors, or ready-to-use packaged controllers. All of these options provide multi-axis control facilities using the Mint motion language.
