The correct motor selection: LSH or LST?

Transcription

1 The correct motor selection: LSH or LST? No matter which variant you have decided on: you have in any case chosen a highquality synchronous servo motor. Because both the LSH and the LSTmotors are equipped with highquality bearings, the unchanged flange, the same insulation system and the same encoder system. In short: the mechanical part is absolutely identical and of qualitatively highest level! because of the socalled compressed winding. Especially in motors with short laminated core the winding overhang usually found in the LST occupies half of the length of the stator. This stator length, that is not required for torque generation, does not exist in the LSHmotor. The LSTmotor differs from the LSHmotor in the design of the stator pack and the number of pole pairs of the rotor. While the LSHmotor is equipped with the new concentrated winding, the LSTmotor trusts in the conventional 6pole stator winding with the familiar properties of a dynamic synchronous servo motor with neodymiumironboronmagnet. Design Rated frequency Motor type LSH Motor type LST compressed winding technology conventional distributed winding Rotor 0pole (exception: LSH050 = 6pole) 6pole design up to 50 Hz at 3000 rpm (exception: LSH050 up to 5 Hz at 4500 rpm) up to 50 Hz at 3000 rpm Concentricity Sizes Moment of inertia very good very good LSH050 to LSH7 LST037 to LST0 approx. 60 % of the LSTmotor 00 % very good good Priceperformance ratio Comparison of torque characteristics The comparison of both characteristics clearly shows the higher torques of the LSHmotor in comparison to the LSTmotor. The stall torque of the LSH is considerably higher than the torque of the LST. Due to the high number of pole pairs of the LSHmotor, it has a high rated frequency. This is why the core losses increase disproportionately with the speed. This is clearly apparent by the extremely descending torque characteristic of the LSH. The magnets of the LSHmotor also enable higher maximum torques than the magnets of the LSTmotor. The comparison reveals that the application is decisive for choosing the appropriate motor type! LSH97 LST97 If high dynamics is an issue, the LSHmotor has its advantages. In standard applications the LSHmotor also convinces with its high power density. Furthermore, the LSHmotor is the winner in the price comparison and with its compact overall length. Despite all these advantages, not all applications can be covered with the LSHmotor. Due to the 6pole design the LSTmotor is generally recommended for applications with rated speeds higher than 3000 rpm. Furthermore, the LSTmotor is the right choice for extreme overloads under static conditions (e.g.: press applications). In case of a desired adaptation of moment of inertia the LSTmotor is able to achieve better regulating properties than the more dynamic LSHmotor. Winding technology This results in a shorter motor with higher torque and up to 00% higher dynamics. Moreover, due to this saving in material and manufacturing efforts we are able to offer the LSHmotor for an almost 0 % lower price. The different properties at a glance: While the LSTmotor has a relatively large winding overhang because of the conventional socalled distributed winding, this does not apply for the LSHmotor,

40 Appendix Holding brake The backlashfree permanentfield singlearea holding brake works in accordance with the stall AC current principle, i.e. the brake needs to energized for releasing. On all LSxmotors the holding brake is mounted directly behind the flange (side A) to provide an optimal holding torque. The holding brake is generally switched on and off during standstill. When using the holding brake as an emergency stop brake you must pay attention to the maximum permissible friction energy (WR). LSH servo motors with holding brake are identified by their type plate. Example: LSH /T,B,R Note: When operating the brake as emergency stop brake the braking torque may be considerably lower than the holding torque. Response times of holding brakes Switching by DCside: Takes place between rectifier and coil, very short overtravel is thereby achieved. For all drives requiring exact braking, also for hoisting gear in particular, DCside switching of the brake is strictly required (break time t =).
