Tec 0.75kW 8 Pole Motor – 100 Frame B5 Flange 28mm Shaft x 250mm Spigot
Tec 0.75kW 8 pole three-phase electric motor with 100 frame size and B5 flange mounting, designed for reliable industrial performance across conveyors, pumps, fans, gearboxes, and general machinery where slower running speed, smooth torque delivery, and dependable continuous-duty operation are required.
This 230/400V 3 phase electric motor is a strong option where direct flange registration is needed for gearboxes, pump sets, fans, and other close-coupled industrial equipment. Its 8 pole design delivers approximately 750rpm, making it well suited to applications that benefit from lower operating speed and stable running characteristics.
Motor Overview
The Tec 0.75kW 8 Pole Electric Motor in 100B5 flange mount format is intended for applications where concentric alignment and direct flange coupling are important. The 250mm spigot and IEC flange arrangement help the motor register accurately onto compatible equipment, which is especially useful for direct-coupled gearboxes, pump sets, and compact industrial assemblies.
Its aluminium construction keeps the motor practical to handle during installation while still providing the protection and rigidity needed for industrial service. This makes the 100B5 version a strong choice for OEM builds and service replacements where a flange motor pattern is required.

Frequently Asked Questions
What speed does an 8 pole motor run at?
An 8 pole electric motor operating on a 50Hz supply typically runs at around 750rpm, with the actual full-load speed usually around 680–720rpm due to motor slip.
Is this motor suitable for gearboxes?
Yes, the B5 flange mount makes this motor suitable for direct registration onto industrial gearboxes, pumps, and other close-coupled equipment designed for IEC flange motors.
What does IP55 protection mean?
IP55 means the motor is protected against dust ingress and low-pressure water jets, making it suitable for most industrial environments.
Can this motor run on an inverter drive?
Many industrial AC motors can operate with inverter drives (VFDs), but suitability depends on the exact application, duty cycle, and motor specification.
What does B5 mounting mean?
B5 mounting means the motor is supplied with a large IEC flange for direct registration onto compatible gearboxes, pumps, and other close-coupled industrial equipment.
