Three-phase spur gear motor: a Siemens 1LA7 squirrel-cage motor with a Stober spur gear unit mounted to it. Motor Brand: Siemens. Motor Part Number: 1LA7090-4AS99-ZS00. Gear Unit Brand: Stober. Gear Unit Part Number: 1951942. Gear Unit Type: C002N0058D90S4. Frame Size: 90S. Poles: 4. Rated Voltage: 220–240 V delta / 380–420 V star. Output Speed: 242 rpm. Output Shaft Diameter: 20 mm. Mounting: foot mounted. Unit Quantity: 1 Pc. Country of Origin: Germany.
1LA7 — the Siemens series for aluminium-housing three-phase squirrel-cage induction motors.
090 — the shaft-height frame size in millimetres, here the 90 frame, executed as a 90S.
4 — the number of poles, which sets the motor’s synchronous speed before the gear unit.
C002N 0058 D90S4 — the Stober gear unit type: helical spur gear unit sized to a D90 S4 motor adapter.
Output Speed: 242 rpm. Poles: 4. Rated Voltage: 220–240 V delta / 380–420 V star. A four-pole motor turns near 1,500 rpm on a 50 Hz supply, so a 242 rpm output speed means the gear unit is reducing by roughly six to one and multiplying torque by the same factor. The dual voltage rating lets the same motor run star on a 400 V three-phase supply or delta on a 230 V supply, which is what makes it usable across European and lower-voltage industrial systems. Output Shaft Diameter: 20 mm, the size the driven coupling or sprocket has to bore for.
Mounting: foot mounted. Frame Size: 90S. Output Shaft Diameter: 20 mm. Motor-to-gearbox adapter: D90 S4.
Unit Quantity: 1 Pc. Motor supplied with the Stober gear unit mounted. Condition: new old stock.
Searchable forms of the numbers: 1LA7090-4AS99-ZS00, 1LA7 090-4AS99-ZS00, 1LA70904AS99-ZS00 and 1LA70904AS99ZS00 for the motor; 1951942, C002N0058D90S4 and C002N 0058 D90S4 for the Stober gear unit. The assembly also carries the Heesemann spur gear motor reference and the number 42821.
