Tec 0.75kW 4 Pole Motor – 80 Frame B14 Face 19mm Shaft x 120mm Spigot
Tec 0.75kW 4 pole three-phase electric motor with 80 frame size and B14 face mounting, designed for reliable industrial performance across conveyors, pumps, fans, gearboxes, and general machinery where compact size, smooth running speed, and dependable torque are required.
This 230/400V 3 phase electric motor is particularly useful where installation space is restricted and a compact IEC face mount is needed. Its 4 pole arrangement produces approximately 1500rpm, giving controlled, smooth-running output for worm gearboxes, small transfer systems, and tightly packaged industrial machinery.
Motor Overview
The Tec 0.75kW 4 Pole Electric Motor in 80B14 face mount format is designed for compact machines that need a smaller flange register than a B5 motor. The 120mm spigot and face-mounted IEC pattern make it a popular match for worm gearboxes, compact reducers, and machinery where overall installation footprint needs to be kept under control.
Its aluminium housing gives a good balance of corrosion resistance, weight reduction, and industrial durability. For OEM designers and maintenance teams, the B14 pattern is often the preferred choice when space-saving gearbox coupling is more important than foot-mounted installation.

Mounting & Installation Benefits
The 80B14 face mounting is useful when a compact flange pattern is needed for close-coupled installation. Compared with larger flange arrangements, the B14 format can help reduce the motor footprint and simplify machine packaging in restricted spaces.
The 19mm shaft and 120mm spigot follow standard IEC motor dimensions, supporting easier replacement of existing B14 motors and compatibility with suitable gearbox inputs.
Why Choose This Motor?
If you need a compact 0.75kW 4 pole 3 phase motor with B14 face mounting, this Tec model is a strong solution for worm gearbox applications and other space-conscious machinery where smaller flange dimensions are beneficial.

Frequently Asked Questions
What speed does a 4 pole motor run at?
A 4 pole electric motor operating on a 50Hz supply typically runs at around 1500rpm, with the actual full-load speed usually around 1400rpm due to motor slip.
Why choose a B14 motor instead of B5?
A B14 face mount motor uses a more compact flange arrangement, which is often preferred on smaller gearboxes and machinery where installation space is limited.
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 B14 mounting mean?
B14 describes this motor’s IEC mounting arrangement and identifies how the motor is designed to be installed on compatible industrial equipment.
