A dairy shed is one of the hardest environments in New Zealand for an electric motor. It is wet, it is washed with acid and alkali, it runs to a schedule that does not move, and when something stops, there is a herd standing in the yard.Most motors in a shed were never specified for it. They were specified on price, and then replaced on a cycle.What a dairy shed does to a motorThe conditions in a milking shed are relentless, and they attack drives from several directions at once.
Twice daily wash down. Plant wash, yard wash, hosing everything within reach. Water goes where it likes, at pressure, every single day of the season.
Aggressive cleaning chemistry. Alkaline wash, acid wash, chlorinated products and sanitisers cycle through the plant and end up on everything around it.
Effluent and slurry. Corrosive, persistent, and it gets into every gap on a housing.
Constant moisture and condensation. A shed is humid even between milkings, and motors that cool down overnight draw damp air in through any breathing point.
Salt air, on a great many coastal Waikato, Taranaki, Southland and Northland farms, accelerates corrosion on everything that is not properly specified.
A season that does not wait. Peak milk does not care that a backing gate drive has failed. Downtime in a shed is measured in animal welfare and lost milk, not just repair cost.
You are a long way from a branch. A motor that has to come from a city, or worse from offshore, is a different problem on a farm than it is in a factory.The pattern most farmers and rural service techs know well is the painted motor that looks fine for a season, rusts under the paint through the second, and seizes in the third.Techtop: a global manufacturer, newly available as a strong alternative in New ZealandTechtop is a family-owned electric motor manufacturer with more than thirty years of production behind it. The group is headquartered in Shanghai's Pudong district, employs around 2,300 people, and runs roughly 191,200 square metres of workshop with automated manufacturing systems.It operates three production facilities and ten jointly owned companies across Europe, the United States, Canada, the Middle East and Australia, producing over two million IEC and NEMA motors a year.For dairy, the practical translation is this. You are not being asked to take a chance on an unknown. You are being offered a manufacturer at global scale that simply has not been the default in New Zealand sheds, because the default was set a long time ago and nobody revisited it.That is the strong alternative. A real second option, stocked in this country, from people you can get on the phone.Built for washdown, not protected from itThe Techtop stainless motor is 316 stainless steel, rated IP69K. That is the ingress protection standard for high-pressure, high-temperature washdown. A lot of the market stops at IP67 or IP68.The detail behind the rating is what makes it last in a shed:
Totally enclosed and non-ventilated, so the body is completely smooth. No cooling fins packed with dried effluent and wash residue. A fan-cooled version is available where the duty needs more heat moved.
A laser-marked nameplate, marked into the steel, so there is no plate edge for muck to sit behind and no plate to corrode off and leave an unidentifiable motor.
Seamless welded feet, so there is no crevice at the mount for water and slurry to sit in.
O-rings between the end bells and the housing. Every connection is sealed in its own right, not relying on one outer seal.
Double lip shaft seals with rotating fingers on the shaft, which is exactly where wash water gets into a conventional motor.
No paint to chip, lift or rust underneath.The range runs 0.18 kW to 7.5 kW, three-phase, in two- and four-pole, which covers the great majority of shed duties.The gearbox has to match, and usually does notBacking gates, augers, feed systems and pump drives are geared applications. Putting a sealed stainless motor on a standard gearbox gets you an assembly that is only as good as the gearbox.Techtop stainless worm gearboxes are available in frame sizes 40 to 90, ratios from 5:1 out to 100:1, with Viton seals and a stainless torque arm where the mount needs one.They are IP69K as well.A matched stainless motor and stainless gearbox, both rated for the wash, from one supplier holding both in New Zealand. That is the difference between fixing the drive and fixing the problem.John Brooks: 62 years alongside New Zealand farmingJohn Brooks Ltd has been supplying New Zealand since 1964. It began with a man who mortgaged everything, bought an old van and started delivering. Three generations later it is one of the established names in industrial motion control in this country, with teams in Auckland, Wellington and Christchurch.Rural New Zealand has always been part of that. Motors and gearboxes on backing gates, augers and pump duties in sheds are not a side line, they are core business, and the people answering the phone have specified them before.John Brooks is the home of Techtop here. Sixty two years of aligning with quality means the same thing today as it did in 1964. Sell the thing that lasts, be straight about what it will and will not do, and be there when it is needed.Helping New Zealand businesses move forward, on farm, means fewer stops, fewer replacements and less time waiting.Stocked in New Zealand. On farm next day.The stainless range is held here, in depth, across Auckland and Christchurch, so the size you need is on the shelf rather than on a boat.Order today and it is processed today.Next day delivery. Consistent availability. Competitively priced.If you are replacing shed motors more often than you should be, or you are specifying a new shed or an upgrade, talk to John Brooks about the Techtop stainless motor and gearbox range. We will match it to the duty and get it to you...
