Complete Catalogue of Motors STK
This document outlines the specifications and characteristics of various STK motor models, including 145STK, 190STK, 300STK, 400STK, 500STK, and 800STK. It details dimensions and technical characteristics, focusing on natural convection and fluid cooling.
STK armatures and rotors can be shipped mounted on a centering flange to ease installation. It is crucial to fix the motor housing on a metallic flange with an area at least twice its section to manage temperature rise effectively.
The document emphasizes managing current losses and temperature rise, recommending specific installation practices for optimal performance. It advises against enclosed environments and suggests consulting for motor derating if necessary.
Fluid cooling is recommended for environments prone to overheating or requiring higher continuous torques. The use of glycoled softened water or approved fluids is specified to minimize corrosion risks.
STK motors are compatible with various brushless drives. The document recommends using drives with digital current loops and anti-resonant filters. It discusses different encoder types, including resolvers, TTL encoders, sin/cos encoders, and absolute encoders, highlighting their advantages and limitations.
Detailed integration guidelines include cable specifications, alignment tolerances, and thermal management considerations. Proper housing and rotor alignment are emphasized, with specifications for fluid input and output configurations.
Technical characteristics for each motor model include rated speed, continuous torque, current requirements, and thermal conditions. Complementary data for fluid-cooled motors specify continuous torque and current requirements at different winding temperatures.
The document concludes with a note on the availability of a full integration handbook and encourages contacting the company for further information or specific requests.
1. Alignment: Rotor/housing alignment must be within +/- 0.1 mm. A mounting tool is available for precise assembly.
2. Cable: Thermal devices cable consists of 2 shielded pairs with a 2x2x0.25mm² section and a maximum external diameter of 7 mm.
3. Diameter Specifications: (De) indicates the maximum diameter passing inside the housing and the minimum necessary for rotor assembly. (Pmax) is the maximum diameter for pieces in contact with the rotor.
4. Tapped Holes: Angular alignment on each side of rotor and housing.
5. Cable Positioning: Allow a +/- 10 arc degrees tolerance around the theoretical position to avoid stressing cables at the motor output.
6. Housing Mounting: Use external centering diameter (B) or internal centering diameters (A).
7. Fluid Pipes: Must be placed opposite wire outputs on the same axial plane.
8. O-ring Grooves: Designed for 3 mm diameter o-rings.
1. Thermal Conditions: Ambient temperature is 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 Fluid: Use softened glycol-added water or approved fluids for closed cooling circuits.
3. Current Specifications: For currents lower than 53 Amps, use one shielded cable; for currents over 53 Amps, use four single shielded wires.
1. 190STK Series: Includes models 190STK2M, 190STK4M, 190STK6M, and 190STK8M with varying specifications for natural convection and fluid-cooled motors.
2. 300STK Series: Includes models 300STK2M, 300STK4M, 300STK6M, and 300STK8M with specifications for natural convection and fluid-cooled motors.
3. 400STK Series: Includes models 400STK2M, 400STK4M, 400STK6M, and 400STK8M with specifications for natural convection and fluid-cooled motors.
1. Cables: Made of PU, class 6, suitable for cable-bearing chains, with a standard length of 2 meters.
2. Assembly Design: Ensure perfect contact between housing and user's bore to avoid thermal issues.
3. Execution Tolerances: For perpendicularity and concentricity, consult the manufacturer.
4. Additional Information: A full integration handbook is available upon request.
The document provides detailed specifications for various models of fluid-cooled motors, including 400STK and 800STK series. Key parameters include rated speed, continuous torque, peak torque, rated power, inertia, weight, thermal time constant, thermal resistance, phase resistance, and inductance. The motors are designed for both natural convection and fluid cooling.
Dimensions for motor housing and rotor are specified, with details on centering diameters, groove depths, and fixation holes. Integration guidelines emphasize proper cable management, alignment tolerances, and thermal considerations. Specific instructions are provided for mounting and fluid input/output placement.
The motors operate under specific thermal conditions, with ambient and winding temperature limits. Fluid input temperatures are critical to avoid condensation, and specific cooling fluids are recommended. The document outlines the use of shielded cables based on current ratings.
The motors are categorized by cooling type, winding code, and precision technology. Codification details include motor diameter, cable length, and mounting flange options. High precision and standard precision technologies are available, with specific cogging percentages.
The document mentions the availability of a full integration handbook and encourages contact for further information or specific requests. It also provides a link for torque vs speed characteristics.
Catalog excerpts
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...
