Product catalog summary

Overview: The document is a technical catalogue for ALXION's Direct Drive servomotors, specifically the ST and STK ranges. These motors are designed for high acceleration and precision in industrial applications, offering a variety of configurations to meet diverse needs.

ST Motors: The ST range includes motors with diameters of 145, 190, and 300 mm, featuring options for hollow, blind, or solid shafts. They provide rated torques from 14.6 Nm to 235 Nm and peak torques up to 1161 Nm. These motors are designed for natural convection cooling and can achieve speeds from 200 to 1500 rpm. They are compact, with a high torque-to-weight ratio, and can integrate various resolvers or encoders.

STK Frameless Motors: These motors are designed for integration into machines requiring large hollow shaft diameters. They offer rated torques from 15 Nm to 2708 Nm, with peak torques up to 10968 Nm when fluid cooling is used. The hollow shaft diameters range from 56 mm to 630 mm, and they are compatible with brushless sinusoidal control systems.

Technical Specifications: Detailed dimensions and characteristics are provided for each motor type, including torque, speed, current, power, weight, and thermal properties. The document includes tables and graphs illustrating the performance and load capacities of the motors under various conditions.

Design and Support: ALXION emphasizes the motors' design for excellent dynamics, accuracy, and reliability. They offer comprehensive technical documentation and support to facilitate collaboration with users during machine design.

Resolvers: ALXION has developed resolvers specifically for their Direct Drive motors, enhancing the accuracy and performance of the servomechanisms.

Note: ALXION reserves the right to modify data without prior notice, and users are advised to contact them for specific conditions or requirements.

Specifications:
The document provides detailed specifications for various motor models in the STK range, including dimensions, alignment, and cable requirements. Key dimensions include housing and rotor diameters, groove depths and widths, and fixation hole sizes. The document specifies different configurations for natural convection and fluid cooling.

Integration Guidelines:
Instructions for integrating the motors include maintaining precise rotor/housing alignment, proper cable management, and ensuring thermal contact between the housing and the user's bore. The document advises on the use of specific materials and configurations for cables and o-rings.

Technical Characteristics:
Technical data covers thermal conditions, torque and speed characteristics, and electrical specifications. The document highlights the importance of maintaining specific fluid input temperatures to prevent condensation and recommends using approved cooling fluids.

Recommendations:
Recommendations include avoiding stress on cables, ensuring proper alignment, and consulting for execution tolerances. The document also offers additional resources, such as an integration handbook, for further guidance.

Data Summary:
Tables provide detailed data on motor performance, including rated speed, torque, current, power, and thermal resistance. The document distinguishes between different motor sizes and configurations, with specific data for each model.

Technical Specifications:
1. Thermal Conditions: Ambient temperature is set at 20°C with a winding temperature rise of 120°C. The stator housing should be in contact with ambient air or integrated with a metallic armature.
2. Fluid Input/Output: Pipes must be placed opposite to wire outputs on the same axial plane. Fluid input temperature should not be lower to avoid condensation.
3. Cooling Fluid: Use softened glycol-added water or approved fluids for closed cooling circuits.
4. Electrical Specifications: Motors are wound for 330 Vac phase to phase. For currents lower than 53 Amps, use one shielded cable; for currents over 53 Amps, use four single shielded wires.

Motor Characteristics:
1. Models: 800STK1M, 800STK2M, 800STK3M, 800STK4M, 800STK6M.
2. Torque and Speed: Detailed torque vs speed characteristics are available online.
3. Power and Inertia: Specifications include rated speed, continuous torque, peak torque, rated power, inertia, and weight.

Complementary Data for Fluid-Cooled Motors:
1. Winding at 60°C and 140°C: Continuous torque, current, fluid input temperature, fluid temperature rise, housing temperature, fluid flow, and losses are specified.
2. Pressure and Cable Specifications: Pressure in bars and power cable dimensions are detailed.

Motor Technology and Codification:
1. Cooling Types: Natural convection, liquid cooling, and integrated cooling jacket.
2. Precision Levels: High precision and standard precision technologies are available.
3. Cable Length and Mounting: Various lengths and mounting flange options are provided.

Catalog excerpts

Designed with the aim of addressing new industrial needs, has created ST low inertia motors range for DIRECT DRIVE allowing acceleration up to 20 000 rad/s. ST range is proposed in three diameters, 145, 190 and300 mm with a variety of hollow shafts up to internal diameter 75 mm, blind shafts or solid shafts. Rated torques cover a wide range between 14.6 Nm and 235 Nm in natural convection, and the peak torque covers from 55 Nm up to 1161 Nm. The motors can reach a rated speed from 200 rpm up to 1500 rpm according to the windings and allow a high regularity of rotation at low speed.Those motors...

Optionally STK armatures and rotors can be shipped mounted on a centering and positioning flange for avoiding the user to make the operation of mounting and centering the rotor inside the stator. > The armature is the source of both current losses and hysteretic and eddy current losses. It will be necessary to take it into account for integrating the motor. Here are the main elements to be taken in consideration:-Permanent torques of the motors are indicated for a copper temperature rise of 120C for armatures in contact with ambient air or integral on all their peripheral area with a metallic...

Various positioning sensor interfaces: the drives can be compatible with 4 kinds of positioning interfaces:-Resolver:The resolvers are in the best cases ( resolver RES FC6 72 32) limited to an accuracy of 1 arc minute. In most of the resolvers available on the market, accuracy is rather around several minutes.It will be necessary to check whether the desired positioning accuracy is compatible with the resolver accuracy and also the electronic resolver-to-digital circuit. On another hand, the resolvers limit the applications due to the crossing hollow shaft. The resolvers RES FC6 72 32 allow a...
