About this Product
The AMTECS 4kW (5.5HP) Three Phase Motor is engineered for reliable, high-efficiency operation in demanding industrial and commercial applications. This 8-Pole (750 rpm) three-phase motor operates on a standard UK 400/690V three-phase supply and features Aluminium 160 frame with B3 - Foot mounting. Rated IE3 efficiency in line with ECO Design Rule 2019/1781, it delivers superior energy savings and lower operating costs compared with single-phase alternatives.
Key features include PTC Thermistors protection for constant temperature monitoring preventing motor burnout from overload, increasing the lifespan and reliability of the motor, a durable terminal box, and multi-mount design for flexible installation. Ideal for powering pumps, conveyors, HVAC systems, and industrial machinery, this three-phase induction motor provides self-starting capability, smooth operation, and high reliability with minimal maintenance. The robust construction handles continuous heavy-duty operation. Supplied with a 12-month warranty and available for free next-day UK delivery.
IE3 Efficiency
Exceeds IE2 efficiency standards for lower energy consumption, reduced running costs and a smaller carbon foot print.
Built-in PTC Thermistors
Constant temperature monitoring prevents motor burnout from overload, increasing the lifespan and reliability of the motor
Multi-Mount Design
Removable feet allows the terminal box to be mounted on the top, left or right for installation flexibility.
Durable Metal Terminal Box
Impact protection and secure capacitor and cable gland entry compared to brittle plastic boxes, ensuring safety in industrial environments.

Three Phase Motor FAQs
Electric motors are normally supplied from the factory wired for clockwise rotation when looking at the drive shaft end. This is the standard factory configuration for most single-phase and three-phase motors.
To confirm the frame size, measure the height from the centre of the motor shaft to the base of the foot, in millimetres. This measurement should correspond to standard frame designations like 71, 80, or 90. Most UK & European electric motors follow IEC frame standards.
A 2-pole motor runs at approximately 3000 RPM, a 4-pole motor at 1500 RPM, a 6-pole motor at 1000 RPM and a 8-pole motor at 750 RPM. The higher the pole count, the higher the torque output but lower the speed.
Yes, all our three phase motors can be used with VFD's (also called Inverters), which allow speed control as well as allowing you to run a 230/400V Three phase motor on a 240V single phase supply.
- B3 (Foot Mount) is the most common configuration, where the feet are bolted to a base/mounting plate.
- B14 or B14S (Small C Face mounted) has a smaller face flange for compact installation with drilled and tapped holes.
- B5 (D Flange mounted) has a large flange for mounting direct to equipment. No feet required.
- B34S (Foot & Small C Face mounted) has a combination of a foot mount and a small face mount for a secure fit with maximum flexibility.
- B35 (Foot & D Flange mounted) has a combination mounting with large flange providing both stability on the ground and a direct flange coupling to the driven equipment.
If you are unsure or would like to confirm the mounting type of your existing motor you can contact our technical team by email (sales@mmengservices.co.uk), WhatsApp or call 01274 288777
All our three phase motors come with a 12 month warranty. Returns are accepted within a 30 day period as long as the motor is new, unused with all its original packaging.
