ALXION SERVOMOTORS for Direct Drive

Product catalog summary

Overview: The ALXION Direct Drive Catalogue introduces a series of servomotors tailored for direct drive applications, focusing on high dynamics, precision, and reliability. It covers the ST and STK motor ranges, detailing their specifications, dimensions, and technical features.

ST Motors: The ST series comprises low inertia motors available in diameters of 145 mm, 190 mm, and 300 mm. They provide rated torques from 14.6 Nm to 235 Nm and peak torques from 55 Nm to 1161 Nm, with rated speeds ranging from 200 rpm to 1500 rpm based on winding configuration. These motors are designed for high torque-to-weight ratios and can incorporate various resolvers and encoders for position feedback.

STK Motors: The STK frameless motors are intended 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 applied. These motors are compatible with brushless sinusoidal control systems.

Technical Specifications: Detailed specifications for each motor type include dimensions, torque ratings, speed capabilities, and feedback options. Motors are available with different shaft configurations, such as solid, hollow, and blind shafts, to meet various application needs.

Key Features: ALXION motors are engineered to eliminate the need for gears, reduce maintenance, and enhance machine performance. They offer high accuracy, no backlash, and noise reduction, making them ideal for precision applications.

Additional Information: The catalogue provides technical support details and highlights ALXION's commitment to collaborating with users during machine design. It also notes that ALXION reserves the right to modify data without prior notice.

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 a metallic armature.
2. Cooling: Motors use natural convection and fluid cooling. Fluid input temperature should not be lower to avoid condensation. Use softened glycol-added water or approved fluids for cooling.
3. Electrical Characteristics: Motors are wound for 330 Vac phase to phase. From 72 Amps continuous, motors are supplied through 4 single wire shielded cables.

Motor Performance:
1. Rated Speed and Torque: Various models have rated speeds of 200 to 800 RPM with continuous torque ranging from 98 to 700 N.m.
2. Peak Torque: Peak torque values range from 387 to 3,520 N.m depending on the model.
3. Power and Inertia: Rated power ranges from 1.05 to 35 kW, with inertia values increasing with motor size.

Integration and Assembly:
1. Cable Specifications: Cables are made of PU, class 6, suitable for cable-bearing chains, with a standard length of 2 meters.
2. Alignment: Rotor/housing alignment must be within +/- 0.1 mm. A mounting tool is available for precise alignment.
3. Design Considerations: Ensure perfect contact between housing and user's bore to avoid thermal issues. Use external or internal centering diameters for housing mounting.

Dimensions and Tolerances:
1. Housing and Rotor Dimensions: Detailed dimensions are provided for various models, including centering diameters and groove positions.
2. Tolerances: Execution tolerances for perpendicularity and concentricity are available upon consultation.

Additional Information:
A full integration handbook is available upon request. For further information or specific requests, customers are encouraged to contact the supplier.

Technical Specifications:
The document provides detailed specifications for OLED motors, focusing on continuous torque, current, fluid input temperature, fluid temperature rise, housing temperature, fluid flow, losses, pressure, and power cable dimensions. The motors are designed for operation at 140°C and 60°C, with different parameters for each temperature.

Motor Dimensions and Integration:
Dimensions for the 800 STK series are provided, including housing and rotor lengths, centering diameters, and groove dimensions. Integration guidelines emphasize proper cable management, alignment, and thermal contact to ensure optimal performance.

Cooling and Thermal Management:
The document outlines cooling methods, including natural convection and fluid cooling, with specific instructions on fluid input temperature and flow rates to prevent condensation and ensure efficient cooling.

Electrical Characteristics:
Details on rated speed, continuous and peak torque, current, power, inertia, weight, thermal time constant, thermal resistance, phase resistance, and inductance are provided for different motor models.

Installation and Assembly Recommendations:
Recommendations include ensuring proper alignment, avoiding stress on cables, and maintaining thermal contact between the housing and the user's bore. Specific tolerances and guidelines for mounting and assembly are also provided.

Additional Information:
The document includes codification for STK motors, detailing motor technology, cooling methods, winding codes, and cable lengths. Contact information for ALXION is provided for further inquiries and access to additional resources.

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...
