Direct Drive Motors and Rotary Stages

Axis New England offers several different direct drive motor and rotary stage solutions from Yaskawa, Parker Daedal, and Parker Dynaserv.  Whether your application requires a load attached directly to a motor or a rotary stage driven by a traditional servo motor, Axis New England has the product to meet your needs. 

Yaskawa 

The SGMCS servomotor line is designed for direct drive applications where the load is directly attached to the motor surface. Direct drive technology eliminates backlash, reduces the number of mechanical components, and provides a stiff mechanical system for highly dynamic applications. Pre-tapped mounting holes and a hollow-through shaft permit a variety of machine designs. These motors have substantial load carrying bearings, low speed windings, and 1,048,576 ppr absolute encoders. 200 volt windings are available with maximum speeds up to 500 rpm. There are 17 sizes available with up to 5,310 lb-in (600 Nm) of peak torque. 

Parker Daedal 

The 200RT Series Rotary Tables are designed for precise motor-driven rotary positioning and indexing. These tables are designed to function independently or in conjunction with linear tables used for precision automation applications. Their low profile design minimizes stack height in multi-axis configurations and enables them to fit in many places where other motorized rotary devices cannot. Models are available in 5, 6, 8, 10, or 12 inch diameters and are offered with four gear ratios making it convenient to match size, speed, and load requirements.  

Parker Dynaserv

The Dynaserv is a family of direct-drive servo systems for industrial and high-tech applications. Direct-drive systems are integrated positioning systems that allow the elimination of mechanical transmissions and allow the load to be mounted directly to the motor. This creates an extremely high performance system that can simplify and increase the performance of many machine types. The Dynaserv G3 is the latest generation drive of the Dynaserv family and provides optimal control of a direct-drive system.

The G3 is an all-new digital drive with implementation of the advanced control and filtering algorithms needed to control a direct-drive motor. The G3 can operate in torque, velocity, or position control modes. The G3 comes with a modern Windows-based software utility that makes the set-up of the Dynaserv system easy and fast via RS232 or RS485 communication. When operated in position mode, the Dynaserv has an auto-tune utility that allows quick and easy setting of the tuning parameters. Digital implementation of the low pass and notch filtering makes mechanical resonance abatement far easier than in earlier models.

Simple motion control functions can be obtained without an external controller. The G3 contains a motion table that allows the storage of indexing moves that can be initiated through a serial command or commanded via discrete inputs. When used with a PLC using multiple inputs, the G3 can be used to achieve high-performance motion and handle complex tasks.

The Dynaserv is UL recognized and meets the requirements for CE certification. The G3 has additional innovative safety features such as a controlled stop after power failure and a servo disable switch on the front panel of the drive. Since the Dynaserv motor is capable of handling very large loads, the G3 has special circuitry to monitor power regeneration to the drive. The G3 is a very flexible design allowing operation of the all the DM series motor models and the standard DR series motors.
