Toshiba Motors and VFDS

Heavy Duty Construction (1)

• Frames are high grade cast iron,

  • Machined to close tolerance to ensure accurate alignment and fit in accordance with our high standards.

  • Exceptional corrosion resistance and high structural rigidity are inherent in Toshiba motor construction.

• Steel fan covers are standard with cast iron option.

• Sintered bronze drain plugs are fitted as standard for frames D160 and above. Available as an option on smaller frames.

Standards

• Toshiba Premium efficiency motors comply with AS1359 and MEPS 2006 requirements.
• Special, motors to other standards are also available eg NEMA, CENELEC or other national standards.

Premium Efficiency Laminations (2)

• Premium-grade silicon steel and longer cores lower operating flux densities and losses achieving optimum efficiency.

Low Loss Stator Windings (3)

• Toshiba's use of greater cross sectional area of copper lowers winding resistance and redcues losses giving improved efficiency.
• All windings are insulated with non-hygroscopic materials, ensuring reliable motor operation in humid, corrosive and abrasive industrial environments.

Insulation and Thermal Advantage

• Toshiba motors are insulated with class 'F' materials and feature excellent thermal reserve, offering low temperature rise characteristics generally below class 'E'.
• These characteristics allow optimal flexibility in regard to variable frequency drives, higher altitude and higher ambient applications, and are also forgiving to intermittent current overloads.

Flexible Terminal Box Design

• Cast iron terminal boxes are diagonally split, and have flanges and neoprene gaskets. Larger frames have oversized fabricated steel boxes.
• All terminal boxes are fitted with removable gland plates, drilled and tapped to dimensions specified on pages 10-15. Blank or customised gland plates are available as an option.
• Terminal boxes may be roated 90¡ by four positions for conduit entry on frames smaller than D315.
• Terminal boxes are mounted right hand side, viewed from drive end, and can be mounted on the opposite side if required on frames up to D225. On frames D250 and above, for non-standard terminal box positions contact Toshiba office at time of order.

Low Noise Levels (4)

• Special attention to the fan and cowl design achieves quiet operation with efficient cooling. Toshiba can supply motors with special low noise level fans and/or acoustic covers.
• Fans are cast iron or fabricated steel depending on frame size.

High Torque Rotor (5)

• Pressure cast aluminium rotors with integrally cast bars, end rings and cooling fans, provide reliable operation.
• Specially designed rotors give Toshiba motors advantageous torque characteristics and minimise losses.

Long Life Bearings (6)
The use of oversized bearings assures long life and quiet operation. Motors in frame sizes up to D132 have sealed bearings. Larger sizes have regreaseable bearings.

Hardware

• All fastenings are zinc passivated for resistance to corrosion.
• Threads are metric.

Output Shafts (7)

• Output shafts are fitted with water/dust exclders.

Durable Nameplate

• Stainless steel nameplate provides complete motor ratings including bearing sizes for quick reference.

Corrosion Resistant Finish (8)

• Toshiba motors are Alkyd resin primed and finished with Alkyd Resin semi gloss. Standard colour is wood smoke grey. Customer specified colours and paint finishes available.

Connections

• All motors are fitted with stud type terminal blocks with 6 (terminations) winding leads. Motors in frames D112 and below may be configured for 240V delta operation, suitable for VVF drives. Motors in larger frames are suitable for Star Delta starting.
• Thermistors are fitted as standard on motors, frame D160 and above and can be fitted on smaller sizes if specified. Thermistor terminals are marked T1, T2.
• An earthing terminals is provided inside the main terminal box, with an additional external earthing facility on all frames.
• Toshiba motors can be supplied wound for voltages up to 1100 volts.
